SIP Phone Audio Problem #2055

Closed fzonno closed 2 years ago

fzonno commented 3 years ago

Expected Behavior

Remote SIP phone We have a SIP PBX (3CX) and some remote phone (STUN mode).

Current Behavior

The remote phones register but there is no audio communication The phones use UDP/TCP 5060 for register and UDP ports 9000-10999 for audio We have a pfSense firewall behind the openmtcprouter with a forward rule any/any. The PBX ports test shows that there is a SIP ALG service active. It can be the problem. Any hints for deactivate it? Any other service / port works perfectly (OpenVPN / HTTPS / SMTP / FTP etc.)

Specifications

Ysurac commented 3 years ago

You can try to disable "Automatic helper assignment" on VPN and WAN zone in firewall configuration.

fzonno commented 3 years ago

I disabled the Automatic helper assignment but the problem persists. Any other clue?

Ysurac commented 3 years ago

No. To my knowledge there is no ALG service on OpenMPTCProuter or OpenWrt.

fzonno commented 3 years ago

I tryed without the pfsense (pbx directly connected to openmptcp but same result. This is the result of the firewall check test image

Ysurac commented 3 years ago

Maybe the problem is on VPS side. Can you try to remove sip related modules: modprobe -r nf_nat_sip and modprobe -r nf_conntrack_sip
