|Description:||We have several Snom Hardphones on Asterisk 1.2.19, sometimes during a call (external/internal) it breaks up with following Warning in the Asterisk CLI:|
WARNING chan_sip.c: Maximum retries exceeded on transmission 3d2cca1cf1b3-c6cbjoxi8rvb@snom320-00041324A7FD for seqno 2 (Critical Response)
****** ADDITIONAL INFORMATION ******
The Problem seems to exist after Version 1.2.13. I allready tried to fix the issue changing "res = transmit_response_with_sdp(p, "200 OK", &p->initreq, 2);" to "res = transmit_response_with_sdp(p, "200 OK", &p->initreq, 1);" (in the chan_sip.c). But there is still the same behavior.

A sip debug is required before we can look at this.

It looks like chan_sip is not processing the 200 OK in response to a NOTIFY... basically a blind transfer happened and the NOTIFY is sent out to say "hey everything went fine"... the Snom sends back a 200 OK to acknowledge receipt of the NOTIFY and chan_sip ignores it.
Can you turn on debug in logger.conf, do a set debug 9 on the console, and recreate it? It should say why chan_sip is ignoring the packet.

I will try it again, problem is - that this Problem happends during a conversation. No blindtransfer was used. The phone rings and suddenly the call breaks up.

Okay - new "Sip-Debug" ist uploaded! :)

Could you please upload a SIP debug that actually shows the SIP traffic? Without seeing the SIP messaging itself, it's going to be difficult to debug.

I am having the same issue. I am also using a snom phone too. Could this be a snom phone issue? What firmware version are you using?
By: Bastian Marmetschke (basty) 2007-07-24 01:41:26
I dont think that this is a Snom Firmware issue. I am using FW from 6.2.3 up to 7.X.X with the same Problem.

Seems to be related to ASTERISK-5175215 and similar bugs - asterisk not being able to distinguish between different simultaneous sip transactions.

Is this also an issue with 1.4?
By: Joshua C. Colp (jcolp) 2007-10-29 12:09:15
Suspended due to lack of response. If this is still an issue feel free to reopen with the needed information.
