Yesterday our phones started performing a remote bridge between our outside network and inside network phones. These go thru a NAT firewall and have been working for a long time. Now we have no audio after about 1/2 a second.
I am seeing remote bridging as examples below. We are also seeing this between our PJSIP trunks and our endpoints. I have no idea how this is working but there is audio. Our SIP trunk is not exhibiting this issue as we have directmedia=no on the SIP config. I cannot find any setting on PJSIP.
We do have our internal and external IP networks defined.
We just started having this issue and I cannot figure out why.
