Hi community,
I am currently trying to enable phone dial-in to a video conferencing system. For this purpose, a service registers an endpoint in Asterik (named after the conference pin) as soon as a conference is started. This works, however after a few seconds, the endpoint becomes ‘unreachable’.
Here is the SIP trace. Does anyone see the problem?
