benasse commented on ASTERISK-26223:
------------------------------------

Below, the steps to reproduce :
* I have a working peer, configured as in sip1.conf
* I delete the parameters related to WebRTC as in sip2.conf
* I do a SIP reload
* When I try to make a call I get the following message in the asterisk CLI :
{code}WARNING[5107][C-00000004] chan_sip.c: Failed to receive SDP offer/answer with required SRTP crypto attributes for audio{code}
Attached is the asterisk full log with the trace of the failed call with the SIP debug.
callid asterisk : C-00000004
CallID SIP : f51acc7c-7893-4f17-bde9-36865e50cf9f

After a restart of asterisk, line working is properly.
