[james (James Zhu)]

hello:
I installed freepbx-15 to test in china, make sip call between two extensions(PJSIP)with LAN, but the rtp address is from 104.145.12.182:5060. no RTP at all. It is a Canada public address. Anyone has such issue?

Not enough logs but Allstream is a Canadian VOIP provider that was bought by Zayo that also owns lots of other VOIP providers. Who is your VSP for any of your tunks. sngrep should show more details

[dicko]

@james

104.145.12.182:5060, Somewhere connecting with sangoma? I do not set SBC and sip trunk, only two sip phone call each other.

In Asterisk SIP Settings, the default value of External Address is Sangoma’s.

For the system to be usable, you must correctly set External Address and Local Networks.

Usually, the Detect Network Settings button will do that. Otherwise, set them manually.

Submit, Apply Config, Restart Asterisk, test.
