Hello,

I can reproduce the error with Snom 370 and FW 7.3.11. An update to
7.3.20 (beta) seems to solve the problem - at least I can't reproduce it
with the metioned scenario anymore.

regards
helmut

Hello again,

I spent some more time investigating the problem. The scenario seems to
be always the same:

- -Phone A calls Phone B on PSTN (OpenZAP+Sangoma) via FS.

- -Call is established and Phone A has a (G722)SRTP connection to FS.

- -After a while (e.g. 14 minutes or 11 minutes or 10 minutes) a call
comes in for Phone A from Phone C via PSTN

- -FS tries to ring Phone A. Phone A response with User Busy

- -FS sends User-Busy via PSTN to Phone C.

- -Right after OpenZAP channel to Phone C is down, FS detects a Error:
SRTP unprotect failed with code 7 (auth check failed) (This happens
only if a total of 9 srtp errors occurs before)

- -Connection from Phone A to Phone B is unbridged by FS

- -PSTN-connection is disconnected with NORMAL_CLEARING


I analysed a time period of  5 weeks. By now I detect this problem only
for exact the scenario I described above. It seems that the problem
applies only to call durations 9-10 minutes and of course SRTP.

I'm on actual svn trunk.

regards
helmut

Hello,


today a colleague of mine told me that sometimes calls were disconnected
without any obvious reasons. In FS's log I found this:

2009-05-07 15:52:22 [ERR] switch_rtp.c:1656 rtp_common_read() Error:
SRTP unprotect failed with code 7 (auth check failed)

I scanned my recent FS log files for that message and found that this
error accours a few times a week. I use Snom Phones all with G722 and
SRTP. Any ideas what this could be caused by?

Hello Helmut,

I also have problems with my Snom300s and Snom320s and G711 and SRTP.
They may be related to this problem, but I am not sure.
The phones disconnect the media stream after a while (2..10 minutes)
because the Snom media port is blocked all of a sudden.
I have opened a bug report at Snom [Ticket#200904081131].

Best regards
Peter
