I must have been playing with the settings on a SNOM 320 because suddenly it cannot connect to FreeSwitch.

I have looked at similar posts and it seems like it must be a codec problem on the SNOM, but I cannot figure it out.

Can someone point me in the right direction?

No its not ALL of the sudden... Please check the SRTP settings on the identity. Thats why you're getting that... the phone defaults to sending crypto in AVP which is invalid... we reject it.

This has been this way for some time I suspect you have updated your snom recently or aren't on 7.1.35 or higher which has the options to fix this on the phone. set it to SAVP


RTP/SAVP: to off will fix it. Unless you're doing SRTP then set it to mandatory.

ironically, snom reported this as a bug to us when we used to tolerate it so they made us fix it thus breaking it on their own phones.

I meant “suddenly” after I had been messing with the SNOM’s settings. The firmware is 7.3.14. The SRTP stuff is:

Symmetrical RTP: off
RTP Encryption: on
Dynamic G.726 payload: on
SRTP Auth-tag: AES-32
RTP/SAVP: off

SEE THIS TAG? If you have SRTP on you MUST put this to Optional if you care for it to work... read the debug a little better it'll tell you to reference an RFC on this also.
