Hi all,

I always get this error message after I hangup a call, what does it mean ?

This means you hungup while asterisk was trying to play a file to you.
It should be of no concern as long as it does not happen during a call.

Re: [Asterisk-Users] Speeding up the dial of DTMF's in SIP channel

2006-03-15 Thread Imran Ahmed
Please Ignore if you cannot edit the code.

You will have to modify app_dial.c in apps directory.
Look for code that calls ast_dtmf_stream(chan, ..., timeout)
The last parameter is the inter digit timeout, it can be set to as low
as 1 (1 millisec) a value of  0 it will default to 100millisecs.
The solution is to add an option to dial application for the timeout
which defaults to the current value(250ms) in app_dial which will
provide for custom timeouts through the dialplan.
Also note that too small timeouts like below 100ms will mess up inband
dtmf tones for example in some zap channels.

 I'm dialing DTMF's in a SIP channel using the options:

 [sip.conf]
 dmtfmode=info

 [extensions.conf]
 exten = _XXX,1,Dial(SIP/gateway,,D(${EXTEN}))

 (this is a custom SIP gateway, which receives the DTMF's sent from
 softphones through Asterisk, and based on them, build the destination
 PSTN number).

 My problem is that Dial send the DTMF's to the SIP/gateway user at a
 rate of about 1 DTMF each 300ms. I'd like to know if it's possible to
 speed up that rate, or even, if it's possible to send the entire
 extension as a single DTMF string.

 Does anybody has a clue about how to do this? I was looking the options
 for the Dial command, and nothing like that appears on it.

 Thanks a lot for your help.

Re: RE : [Asterisk-Users] lists problem, Gmail????????

2006-02-13 Thread Imran Ahmed
I have experienced similar problems using gmail.
Gmail certainly had some problems with emails from asterisk lists.
I donot know if it was only restricted to asterisk lists.
As not all emails were being delayed (or dropped), some of you might be under
the impression that theres no problem.
Please compare your emails with the list archives to be sure you didnt miss
something important.
Also, the problems seems to have gone away this week.

Imran

 Personally I use gmail, but use a different email address that is

 like how it groups conversations (probably why you see a lot of gmail

Re: [Asterisk-Users] echo cancel from telco

2006-02-07 Thread Imran Ahmed
 here is a little explanation:

 End user (You) - Your Telco -- Carrier 1 ---
 Carrier 2  Carrier 3 --- Carrier 4(PTT)
 ---  Far End User

 So basically, the Echo cancelling work backwards usually cancellation
 for you would be done by Carrier 4, 3, 2, 1, or your Telco in that order
 and echo for the Far End User would be done by Your Telco, Carrier 1, 2,
 3, or 4 in that order.

 Why in that order?


AFAIK, the order is exactly the opposite, and if the user is
experiencing echo on the sip phone, its most likely that the other end
is the source of echo, which should be cancelled by the telco because
its is nearer to the source of echo than the sip phone gateway.

Re: [Asterisk-Users] meetme and dtmf

2006-02-02 Thread Imran Ahmed
  Step 3 The Iax client heve to send some other DTMF to the IVR.
 
 
  How is the IVR still involved if the call has been transferred into a
  conference room?
 
 The IVR records the conversation between the other partecipant to the
 conference and wait '#' to stop recording and a '1'  to save the file.

may or may not work, try at your own risk:

1) Use a sip soft phone and set the dtmf mode = inband.
2) In asterisk set the dtmf mode for that soft phone to be rfc2833 or
info. (this is done so that asterisk ignores the inband dtmf on the
sip channel).
3) Design your dialplan such that asterisk should not depend on dtmf
from the sip call.
ex:

exten xxx, 1, dial(zap/g/client_number) //on answer directed to conference room
exten xxx, 2, dial(zap/g/ivr_number) //on answer directed to conference room.
exten xxx, 3, meetme(conference room)

once the sip call is in the conference then the ivr will detect dtmf
from the audio data. Note that before the sip call is in a conference
dtmf will not be detectable by the ivr or asterisk, and Ofcourse, this
is not tested and only a test can confirm if it works.

drawbacks: dtmf will not be available to ivr until your call is in
conference. asterisk will never see any dtmf (which should be okay in
this specific case).
dtmf tones are not squelched so the other user in the conference will
hear dtmf tones.

Re: [Asterisk-Users] meetme and dtmf

2006-02-01 Thread Imran Ahmed
 AFAIK there's no DTMF option in IAX2...

 IAX always sends DTMF inline, eliminating the confusion often found with
 SIP.
 http://www.voip-info.org/wiki-IAX

Even though no IAX client supports inband dtmf, An IAX client can send
inband dtmf which would have corrected your problem.
The problem here is with the meetme application when dealing with non
zaptel channels it does not have a mechanism to enable dtmf to pass
through the conference unless dtmf is inband (i.e. part of the audio
stream).
The following are the solutions
a) Use a SIP phone with inband dtmf (No guarantee this will work either)
b) Modify meetme to broadcast dtmf to all channels in conference( All
channels will work in this case).

 No, it won't. No IAX2 client will start a DSP to listen for inband DTMF,
 because IAX2 is defined to always send out-of-band DTMF.

 At best, if the receiving IAX2 system is just passing the audio along to
 another protocol that does support inband DTMF, then sending it in the
 audio stream would work. If the application receiving the DTMF is on the
 other IAX2 end, though (like MeetMe in this case), then it will never
 'see' the DTMF, because Asterisk will not look in the audio stream for DTMF.

I agree, but the other ends of the conference were zap channels in
this case, at least that is what I figured by the first email.

 Here is my problem, at this point the IVR doesn't hear the dtmf sended

I donot know if IaxComm has inband dtmf mode available, if so enable
it and see if it works.

Re: [Asterisk-Users] Pri Gateway Hardware

You donot need multiple asterisk boxes for a single t1. A single p4
box should be helpful, you can use digiums te110p pci card for a
single pri line into the box. The same  box could also be on another
network dealing with SIP.

 All that you need is at least two boxes:



 1 is going to be the PRI Asterisk box, which interfaces with the outside

 Does anyone have any experience using a PRI gateway, I am looking for a way

 I herd there are copper gateway devices (like a X100P card, only it
 registers with asterisk using sip, and it doesn't have to be physically
 connected to the box)  Does anyone have any experience with a PRI gateway?
 And could tell me the cost and the quality? Thanks
