asterisk users - Feb 2004 - Problems with chan_sip: random calls have no sound withouth any errors

Hi All,

I have been busy with this problem for a while now, but I can't find any 
solution. First I thought this was a problem with the phones, but all my 
phones have this problem. (2 SNOM 200, 2 GS 102, 2 Cisco 7960). I tried 
all firmware versions I could find for the phones.

First, my situation:
- No NAT, No Firewall, same subnet
- Codec configuration:

In general:
disallow=all
disallow=g723.1
disallow=g729
disallow=gsm
allow=ulaw
allow=alaw

In the phones:
disallow=all
disallow=g723.1
disallow=g729
disallow=gsm
allow=ulaw
allow=alaw

But I also tried other codec configs. (allow=gsm, etc). Same problem. 
I'm testing from the Cisco 7960, as this phone seems to work best. I 
could also test from another phone with the same results. The S is for 
Success (can talk), the F is for Failure(Call gets setup but no 
speech/sound).

Cisco 7960 to SNOM
S,S,F,S,F,F,F,S,S,S,S,S,F

Cisco 7960 to GS
S,F,S,S,F,S,S,F,S,F,

I placed a sip debug from asterisk for each situation at the following URL:

http://audix.noc.ams-ix.net/asterisk/dumps/

- cisco_to_gs_failure.txt
- cisco_to_gs_success.txt
- cisco_to_snom_success.txt
- cisco_to_snom_failure.txt

Somebody have a clue? I'm thinking of filing a bug but I want to make 
sure this is no configuration or other problem at my side.

Thanks and kind regards,

Geert Nijpels

Asterisk is still saying it accepts G729.  That is prolly the problem. 
Try updating to the latest CVS of Asterisk or to Asterisk version 0.7.1.

If there any reason you are allowing both ulaw AND alaw.
