No response to INFO requests

Hi, we’re using asterisk 1.8.13 and my SIP provider is sending periodic INFO requests. Asterisk seems to be totally ignoring the request and is not sending any response. I believe a simple OK response would be fine in this case.

Because we’re not responding our provider is setting some other flag thinking something is wrong and disabling our trunk.

Has anyone else seen this before?

Asterisk should respond to INFO requests, although the response will only be OK if it is valid in context, which may mean in dialogue, with a DTMF payload.

You need to use sip set debug on and determine whether Asterisk is receiving the message and how it is responding. If it really isn’t responding, you will need to turn up the module debugging on chan_sip.
