Make sure the Grandstream RTP port ranges line up with your Settings->Asterisk SIP Settings ranges. 5004 sounds device specific. The default for FreePBX, is, I think, 10000-20000. Are you using OSS Endpoint Manager? If so, see if the template has an RTP range setting as well. If you are only seeing one endpoint’s IP address in the RTP debug, then it sounds like the other endpoint isn’t finding something mutual agreeable. I HATE RTP issues. SIP always seems fairly straight forward. FWIW, I’m all PJSIP on FreePBX 15 (even trunks). It is where they’re going so I just bit the bullet and hammered it out. Once up and going, it does seem to be fairly robust.

I've tried changing PJSIP to Chan_SIP; the phone wouldn't register:
[image: old_sip.jpg] The top status is one of the extensions registered as PJSIP, the bottom is one after switching to Chan_SIP - it won't register. If I turn rtp debug on, I get a series of: Sent RTP packet to 192.168.200.40:5004 (type 00, seq 019554, ts 085649, len 000160) Nothing else is reported. The mystery continues.
