Greetings Ron-

Just wanted to give you a heads up about an alternative SCCP channel driver 
available for Asterisk. Please see here:

http://freecode.com/projects/chan-sccp-b

I have no experience with it (nor SCCP in general) but just wanted to give you 
an option in the event the included SCCP driver does not give you satisfactory 
results.

chan_local does not have a mechanism to do this.

Hi All,

I have a Polycom Handset on a front door and I'd like the phone to dial a 
number as soon as the handset is lifted without having to press and buttons or 
enter any numbers.  I know how to do this on a Linksys but I can't find out how 
to do it on a Polycom.

I would be greatly appreciate is some is able to tell me how this is 
accomplished.

[asterisk-users] asterisk with ss7 voice broadcast

2012-06-14 Thread [Digital^Dude] ®
Hello,


Asterisk under  90% load of SS7 calls can only withstand the voice
broadcasting for 30 minutes. After around 30 minutes, it stops receiving
any call hits via AMI. No errors are reported. Giving it a minute's rest
makes it work for another 30 minutes.

Can anyone hint to what may be causing this?

Thanks

[asterisk-users] Dualstack

2012-06-14 Thread Pawel Kuzak
I have an Asterisk (v10.2.0) running and bound to address ::. I think 
this way he listens and answers to requests send to the IPv4 and IPv6 
address (haven't check that with IPv6 yet). What I want to achieve is, 
that he handles signaling via IPv4, but RTP via IPv6.
In my setup, I have a user agent (Dualstack) that generates an INVITE 
and sends it out via IPv6. In the SDP part the user agent expects the 
RTP traffic on its IPv6 address as well. Between the user agent and the 
Asterisk, I have a proxy that handles the signaling part, and translates 
from IPv6 to IPv4 and vice versa. The Asterisk accepts that request 
(IPv4) and does everything well, except that in his SDP offer, he 
inserts his IPv4 address (I think that's because he received the request 
via IPv4).

The result of this is:
The user agent sends RTP traffic via IPv4 to the Asterisk.
The Asterisk sends RTP traffic via IPv6 to the user agent.

Signaling: UA  (IPv6)  Proxy  (IPv4)  Asterisk
RTP: UA --- (IPv4)  Asterisk
UA - (IPv6) -- Asterisk

Does anybody know how I can achieve that Asterisk does input his IPv6 
address in the SDP offer and uses that for incoming RTP, if he sees, 
that the user agent also uses an IPv6 address in his SDP offer?
Maybe there is an easy way and I've just overseen a configuration 
option. Or do I have to patch the sources?


Thanks in advance!

Assuming that the same address can be sent to all user agents that
communicate with that Asterisk instance, the media_address setting could
potentially be used to specify an IPv6 address to send media to, while
keeping the signalling on IPv4.

Re: [asterisk-users] Differences between PBX and SBC

2012-06-14 Thread Andreas Sikkema
 That's my question...the sbc provides security over trunking, right? The
 same can do Asterisk or a Proxy..isn't? Does an SBC can provide any kind of
 add-value to an Asterisk deployment?

A PBX provides functionality to users. An SBC *can* secure a PBX
against the outside world, but that is configuration dependent. The
more powerful the SBC, the more configuration it requires to make
things work, let alone secure whatever it is supposed to protect.

An SBC is in essence a B2BUA, looking quote a lot like a really simple
pass through Asterisk configuration.

Is the chan-sccp-b project the same one that got put in SVN of 1.8 branch?
I have not been able to find anything definitive that says so, I really

[asterisk-users] Asterisk 10.5.1 Now Available (Security Release)

2012-06-14 Thread Asterisk Development Team
The Asterisk Development Team has announced a security release for Asterisk 10.
This security release is released as version 10.5.1.

The release is available for immediate download at 
http://downloads.asterisk.org/pub/telephony/asterisk/releases

The release of Asterisk 10.5.1 resolves the following issue:

* A remotely exploitable crash vulnerability was found in the Skinny (SCCP)
  Channel driver. When an SCCP client sends an Off Hook message, followed by
  a Key Pad Button Message, a structure that was previously set to NULL is
  dereferenced.  This allows remote authenticated connections the ability to
  cause a crash in the server, denying services to legitimate users.

This issue and its resolution is described in the security advisory.

For more information about the details of this vulnerability, please read 
security advisory AST-2012-009, which was released at the same time as this
announcement.

For a full list of changes in the current releases, please see the ChangeLog:

http://downloads.asterisk.org/pub/telephony/asterisk/releases/ChangeLog-10.5.1

The security advisory is available at:

 * http://downloads.asterisk.org/pub/security/AST-2012-009.pdf

Thank you for your continued support of Asterisk!

   Asterisk Project Security Advisory - AST-2012-009

  Product Asterisk
  Summary Skinny Channel Driver Remote Crash Vulnerability
 Nature of Advisory   Denial of Service   
   Susceptibility Remote authenticated sessions   
  SeverityMinor

  Last Updated On June 14, 2012   
  Advisory ContactMatt Jordan  mjordan AT digium DOT com
  CVE NameCVE-2012-3553   

Description  AST-2012-008 previously dealt with a denial of service   
 attack exploitable in the Skinny channel driver that 
 occurred when certain messages are sent after a previously   
 registered station sends an Off Hook message. Unresolved in  
 that patch is an issue in the Asterisk 10 releases,  
 wherein, if a Station Key Pad Button Message is processed
 after an Off Hook message, the channel driver will   
 inappropriately dereference a Null pointer.  
  
 Similar to AST-2012-008, a remote attacker with a valid  
 SCCP ID can can use this vulnerability by closing a  
 connection to the Asterisk server when a station is in the   
 Off Hook call state and crash the server.  

Resolution  The presence of a device for a line is now checked in the 
appropriate channel callbacks, preventing the crash.

[asterisk-users] Digium IP Phones - Teleworker Capability?

2012-06-14 Thread asterisk users
We couldn't see anything about this on the Digium site, but maybe
someone here can comment?

Do the new Digium phones provide good teleworker functionality?

The benchmark we're comparing against is the capabilities of Mitel
3300 IP systems  with Mitel 5330 IP phones (running their proprietary
MINET protocol), specifically:

a. A Mitel phone can be easily configured for teleworker mode (select
TW mode and the IP of the gateway server).  The phone reboots and it
is ready to be used (once the Mitel border gateway is set to recognize
the unit's ID, based on its MAC address, printed on the label on the
back of the phone).  If the phone gets reallocated back to a directly
connected office environment, a simple reset procedure brings it back.

b. You can plug in the phone virtually anywhere. It has a built-in
tunnelling mechanism providing end-to-end encryption and is very
tolerant of the network configuration, routers, NAT, etc.

c. If the link between the phone and the gateway goes down, the phone
will restore itself gracefully and automatically once the network
function resumes.  Absolutely hassle-free to the user.

d. Users can be configured to have hot-desk functionality.  The phone
has a default extension assigned, but the user can be set up so that
they can log in to their normal office extension number from
wherever they are.  Their office phone is automatically logged-out and
goes to its default extension when you log in to a teleworker phone
(you don't have to log out from it first).  Your phone buttons,
display settings, voicemail WMI and access, (everything) move to this
new phone, and you can work from your home office, on the road, etc.,
and inbound and outbound calls work just like you were there in the
office (callerid, etc).

These four features would be a big selling point for us to consider
moving our organization from Mitel to Digium/Asterisk/Switchvox.

How much of this can be done with Asterisk/Switchvox and, say, the
Digium D70 phone with dynamic button display?

Thanks for all comments!

Digium phones speak SIP and RTP to the server, just like pretty much any

I don't understand this; SIP phones don't require this at all. The phone 
is an intelligent device on its own. If there is no network connectivity 
to the server, then calls cannot be placed or received, but once 
connectivity is restored, operation would be back to normal.

This is pretty good news, overall. To comment on Kevin's points:

- The end-to-end encryption is important to us, because
client-ID-sensitive information is part of our environment.  Something
like built-in OpenVPN would work for us, if that were an option.

- Being fault-tolerant (of less than perfect DSL and rural-wireless
connections - if the boss is at his cabin, for instance) and being
very user-friendly about it is really important to end users.  Minet
has a heart-beat mechanism so that if the connection goes down between
the phone and the switch, the display shows it.  Of course, calls get
diverted to voicemail during that period.

If something is not working in the network, the user is informed about
it, and when it is fixed, everything continues, including button DSS
status updates, voicemail WMI, etc.

On typical SIP phones, everything looks normal until you go to use it,
then there is no dialtone, or you just get dead-air on the handset).

Our users are pretty demanding, and want a utility-grade solution that
will always work - for them.

-  Most of it, I think. Give them a try!

Is there a detailed application note in the Digium wiki (or anywhere
else for that matter) about these implementing features under
Asterisk/Switchvox?

Thanks!

 client-ID-sensitive information is part of our environment.  Something
 like built-in OpenVPN would work for us, if that were an option.
 

Yealink and I think Aastra phones have OpenVPN built in.  We use Yealink
with layer 2 tunnels such that the phones have the same configuration,
network wise, wherever they happen to be plugged in.  No NAT issues
ever.

 - Being fault-tolerant (of less than perfect DSL and rural-wireless
 connections - if the boss is at his cabin, for instance) and being
 very user-friendly about it is really important to end users.  Minet
 has a heart-beat mechanism so that if the connection goes down between
 the phone and the switch, the display shows it.  Of course, calls get
 diverted to voicemail during that period.
 

Pretty much all SIP phones work that way.

 If something is not working in the network, the user is informed about
 it, and when it is fixed, everything continues, including button DSS
 status updates, voicemail WMI, etc.
 

Again all phones work that way.

 On typical SIP phones, everything looks normal until you go to use it,
 then there is no dialtone, or you just get dead-air on the handset).
 

Which SIP phone have you been using?  The ones we are familiar with -
Polycom, Linksys, Yealink, Snom, Aastra, Grandstream - all show you when
the network link is down, and all services return as soon as it comes
back up.  Even Linksys ATAs at least show you an LED of when the device
is registered, though you will just get dead air if you pick up the
handset.

 Our users are pretty demanding, and want a utility-grade solution that
 will always work - for them.
 
 -  Most of it, I think. Give them a try!
 
 Is there a detailed application note in the Digium wiki (or anywhere
 else for that matter) about these implementing features under
 Asterisk/Switchvox?
 

You could probably find 50 people to help you set such a system up on
this list (or more appropriately on -biz).

Cheers,

j

 I have a Polycom Handset on a front door and I'd like the phone to
 dial a number as soon as the handset is lifted without having to
 press and buttons or enter any numbers.  I know how to do this on a
 Linksys but I can't find out how to do it on a Polycom.
 
 I would be greatly appreciate is some is able to tell me how this is
 accomplished.

[asterisk-users] Does Asterisk support AMR and AMR-WB

2012-06-14 Thread Jakson Kalsson
Hi all, I have a project for the 3G related, AMR and AMR-WB support.

I'm using the client develop suite from the PortSIP(http://www.portsip.com),
as their said
support the AMR, AMR-WB with RFC4867.

Now I have to setup a SIP server/SIP PBX in our Lab for test, does the
Asterisk
support these codecs and RFC4867 ? If no, there has any  plugin to support
this ?


Also, any other Server/PBX which support AMR, AMR-WB recommended are
welcome.



Best regards,
