I'm having echo too - ISDN-PRI using a Sangoma card to the PSTN. My SIP outgoing calls have an echo about 80% of the time, but only on a local T1. It only an echo to the SIP caller; the called party never hears the echo. I have a second T1-PRI (port 2 of the same card) to a long distance carrier with no echo problem, ever. Played around with all the echo stuff, you identified below. Seems there is much ambiguity on the guidance as much of the echo suggestions apply only to analog lines. It's unclear how there can be an echo on a T1-PRI (digital) anyway.

Subject: [Asterisk-Users] Re: Incoming echo cancel



Same problem here: if call come over ISDN PRI and it is for a SIP phone that equals to strong echo situation, at the SIP end. Interestingly this doesn't happen on all calls but it does on 95% of them. Asterisk load at that moment is insignificant - 1 to 2 calls.

I have tried with all possible echo cancellers in zconfig.h, with and without MMX, and with and without CFLAGS+=-march=i686 in zaptel Makefile, but without any success.

TE110P is on its own interrupt - no other cards on board except Intel chipset PCI LAN card (on shared interrupt) and machine is Intel 685 chipset based, with P4 Celleron 2.6 GHz, 1Gbyte RAM, WD 10K RPM IDE HDD.

I have even contacted Digium support with this issue, but except a request for some additional explanations of my setup, nothing from them so far (for about a week).

Anyone have an idea, why this type of echo happens ? As far as I have read on the lists this type of echo should not occur at all, but it simply does !

Hi,


I'm having the same problems in echo cancellations that are mentioning in this mail of the list http://lists.digium.com/pipermail/asterisk-users/2003-July/016073.html , but I haven't found some reply to this mail.

I haven't echo problem on outcoming calls but echo cancellation is
disabled in zaptel channels in incoming calls. Status of zaptel channel
is the next:

I don't know because Asterisk doesn't enable echo cancelation.

Hi Herman,

Look at the bottom of your phones and compare the REN values of both. Do
they both value of REN 1.0?  I think the one with the problem might have
an REN value other than one.  You tell me!

Obviously, your ISDN gateway is misconfigured somehow. I would suggest
that you configure the gateway to dial some extension on your * box and
see if incoming calls work. If they don't, then there is a problem with
configuration of gateway's ISDN interface. If incoming calls work, then
it is possible that the gateway is rejecting outgoing calls based on
number called (I had that problem once), or perhaps you just forgot to
pay the bill to your mobile operator :)).

Hi all,

The probel I encounter is that when trying to dial a phone number,
I've the message : unable to create a zap channel.

My card is normally well configured because when connected to the NT,
It works perfectly...  The gateway is configured as a NT as well so no

Has anyone an idea of what I should look for ?

Hello,

we're in process of testing an interconnection with a trans-european
carrier. But the carrier wants the SIP signalling to server 1 and the
RTP stream to server 2. How do I configure asterisk to work with that
type of installation. It seems they are using NexTone as SIP Signaling
and RTP servers. Can someone help me???

   - the PCI ID of the card seems to change over time which means that
loading the module does not always recognise the card, only way to reset
this is to power cycle the machine

I noticed this behaviour as well. i thought it was my motherboard wrongly assigning irq values - the symptoms i noticed were:

irq value set by me - machine starts, module loads, all functional
reboot
irq value reset to another /shared/ irq - machine starts, module fails
reboot
irq value set by me again -  machine starts, module fails
check irq - it has been reset to something else
irq value set by me - machine starts, module loads, all functional

unfortunately my bios doesn't allow manual assigning of irqs - i have to
swap them arond based on the ones it gives me...
i ended up disabling my usb bus as i don't need it...

i can't find any consistency to it and am living in fear of the reboot..
very odd..

To: Asterisk Users Mailing List - Non-Commercial Discussion
<[email protected]>
Message-ID: <[EMAIL PROTECTED]>
Content-Type: text/plain; charset=US-ASCII

Hi Folks,

I found a strange problem trying to install a system on a customer. I
have the following network configuration:

Asterisk - Router (NAT) - Internet - Router (NAT) - Grandstream Phone

The routers are low end D-Link router + broadband access. The router
near asterisk has 5060 and 10000-10009 ports opened and assigned to
Asterisk server. The router near the phone has default configuration:
outgoing ok, incoming blocked.

I have Qualify = 1000. As soon as * is restarted I get a message
telling the phone is unreachable. Looking at SIP debug I see *
transmitting OPTIONS and receiving OK but it seems that * discards the
OKs, because it always transmits OPTIONS 4 times (and receives 4 OKs),
stop a little and begin transmitting OPTIONS again.

Looking at the SIP messages I found that the Call-ID in the OPTIONS
message uses the Asterisk EXTERNAL IP address but the OK coming from
the GS Phone has its Call-ID with the Asterisk INTERNAL IP address.

I run ethereal near the phone and the OK it sends has Asterisk
EXTERNAL IP address! Somebody is translating the EXTERNAL IP into the
INTERNAL IP at the Call-Id header.

I also run tcpdump at the Asterisk Server and the result is the same
as the sip debug.

My simple conclusion is: the router is opening the SIP message and
translating the Call-Id header IP, but I don't believe in that.

Any clue?

Thanks?

Renato

Solved!
The problem was that "capiinit start" can only be done by user "root" and
asterisk is started as user "asterisk".
Once I edited sudo ("visudo") and gave permission, the problem was solved.

Hi all!

After much struggling I got my [EMAIL PROTECTED] working fine AND making use of 
two
AVMFritz!PCI cards. Really nice !  (kernel 2.4.2x)

There's however a silly glitch that's getting on my nerves, and, kind of a
newbie that I am to linux, it should be easy to get help :


-- "capiinit start" MUST BE run before Asterisk. (any other way makes *
not
to start because chan_capi doesn't find CAPI support)

You must find this an easy thing, as I did. So I entered /etc/rc.d/ and
inserted "capiinit start" to start as early as possible. Also added some
lines of junk text so to see them going by as the system boots...

What's making me desperate is that the lines go by, capiinit is, in fact,
runned, and Asterisk still fails in the end.
I login and type my very first command "asterisk -vvvc" and it then starts
with no trouble.


Is this strange or what ?

Thanks in advance for your help.

M.G.

Subject: [Asterisk-Users] One single record file for a meetme monitor?
To: [email protected]
Message-ID: <[EMAIL PROTECTED]>
Content-Type: text/plain; charset=us-ascii

I'm trying to figure out the best way to record a
conference.

Many people suggest something like this:
exten => 2060,1,Answer
exten => 2060,2,Wait(1)
exten => 2060,3,Monitor(wav,myfilename)
exten => 2060,4,Meetme(1,ps)

However, this creates two files for each user that
connects to the meetme.  (I know they can be mux'd
together to make one with sox..I've done that too)
However, you still get 10 files if 10 users enter the
meetme.

I'd really like to be able to simple record a single
file with all the channels mux'd together.

Someone suggested executing a script and having the
monitor application join the meetme.  However, I have
yet to see this work correctly.... and it isn't the
best solution because I've got to have some logic to
add the local listener when the first person enters...
and exit when the last person exits.

Anyways, just wanted to see if any of you have this
worked out already.  I really think there should be an
option on the meetme.

Thanks,
Dave

They seem the same but just in case.

Asterisk does not see anything coming in on the D channel. What does zttool say about the state of the link?

As I said before, if the card is an isdn card you need to use ccs
signalling. Cas signalling is unusual, but possible, over an E1. Can you
find out the model number of the E1 card in the Panasonic pbx?
