Hey,

We have several grandstream 2160 with firmware 1.0.7.25.
At this moment we have trouble with receiving calls on GXP 2160
When taking a call, call terminates.
Message in operator : WARNING[1994]: chan_sip.c:21103 in handle_response_invite: Received response: "200 OK" from '211' without SDP

Best regards,
HB

Hi,

the warning means that the GXP answered the call, but did not send back any information about audio (rtp ports, codecs, etc). Either the phone is misconfigured (=>factory reset it) or broken (=>upgrade/downgrade it).

Tried this with several phones.
Manually provisioned, and provisioned by kerio operator, but always the same problem.
No problems with GXP 2170.

I think you should try Grandstream's support about this. If the phone is not sending the SDP, it's certainly an incorrect behavior. Based on our past experience with Grandstream's support, they are quite responsive.
