[Freeswitch-users] Issue: INCOMPATIBLE_DESTINATION / AUDIO RTP REPORTS ERROR [Missing local host]

Fri Nov 20 10:51:50 UTC 2020

Hello,

Sorry for delay, i had to catch up on a few things a bit.
Instead of 79.x.x.x. it should be 10.20.30.41 .... and yes this is what i
expect to have.

But i still don't know why FS generates such an event.
As for workaround i use "bypass_media=true" instead of "proxy_media=true",
but the question is how to solve it.

Thanks
Maciej
