[OpenSIPS-Users] rtpengine aborting loop when reinvite is sent

[Mario San Vicente]

Hello Alex,

I tried the flag loop-protect and it works.

I get the following message on the logs:

rtpengine[22968]: INFO: [fd72c95927567a5b]: Ignoring message as SDP has
already been processed by us

Thanks for your inputs!

Regards
