[Asterisk-Users] Problems w. chan_capi + ztdummy
Hi Everybody I've got a weird problem. I am running one Asterisk system on a dual processor box. This box mostly do VoIP only but it has a Fritz PCI ISDN card installed with latest drivers. Dialing out through the ISDN cards from an internal Snom phone works fine and so does dialing in. Except - if I load the ztdummy module (for IAX channels) the capi drivers starts acting up. It is hard to describe the sound but it breaks up so badly that it is impossible to understand the voice prompts and they also start playing extremely slow (demo congrats alone takes more than 30 seconds before going to the next prompt in the standard demo setup). I am nearly updating this particular box every day and within the last couple of days something else has happened. When dialing OUT on the ISDN card everything works fine. When someone dial IN through the card and connect to the internal Snom phone there is a pulsating background noice that can only be heard on the VoIP phone. From outside (the ISDN) things sound perfect - from inside you can still hear what is being said - but there is that pulsating quite high noice. Any ideas?

[Asterisk-Users] Problems w. chan_capi + ztdummy - SNOM Problem?
Actually I've played around with the last issue quite a lot and this is indeed getting weirder. Let me try to describe the problem. sip.conf is configured with: disallow = all allow = gsm allow = ulaw allow = alaw Snom phone is configured to use GSM as default codec but with "Offer Answer/Full" option set. If I place a call FROM the Snom phone to an external number (going out of the CAPI/Fritz/ISDN interface) everything works beautifully - and "sip show channels" show that the Snom phone is using GSM. If a call come IN on the Capi interface and is routed to the phone there is the described pulsating sound heard on the Snom phone alone and "sip show channels" report that ALAW is being used as codec. How come the choice of codec is different? AFAIK when gsm is first in sip.conf this should be the preferred codec. I haven't tried to roll back to an earlier Snom image (using 2.05d) but this problem is definitely a new one. Using an Asterisk CVS-HEAD as of today. So - I am not sure exactly where this bug is. As far as I can see there might be two problems - one that the codec of my choice is not the one being used. Second the pulsating noice when using ALAW (which should work fine too). Any ideas?

There is some sort of support of G7231 in openh323? I have seen a file in src but I think that there is only a interface not an implementation and this interface is using some itu files (free code from itu). Anyone using the G7231 in openh323?
