3CX and musimi, no sound on incoming calls

[Dark One]

Hi

I have a setup with 3CX and musimi VOIP provider.
I have opened UDP for stun, sip and rtp ports according to my PBX setup.
Ringing out makes no problem and all works, so does internal calls.
But when i cal from my cell to the sip number, i can make connection but there are no sound throug the line.
I obviously have made some error
Any ideas?

Witch ports (how many) have you opened?

List of default ports used by the 3cx phonesystem:
5060 (stanard sip port) TCP/UDP
5061 (secondary sip port) TCP/UDP
5480 (portgre) (only on local machine)
5481 (apache) (only on local machine)
5482 (media server) (only on local machine)
3478 (STUN Server) TCP/UDP
7000-7500 (Default port for internall calls) (only on local machine)
9000 - 9003 (ports for external calls through VOIP Gateway) UDP
10000-20000 (RTP ports) (Used if no stun available for audio)

Re:

Have the same problem. No ringing tone/music on hold when I dial inside numbers. No problem for outbound calls.

please give us the call related part of the incomming call and a example for a outgoing "good" call from your server log.

perhaps we can see what happens.

I have opened following ports in ISA

3874 tcp -outbound
3874 udp send/rec
5060 - 5062 tcp -outbound
5060 - 39999 udp send/rec

that should cover the ports quite well

Allow non-sequental RTP port is set to check

i still can't figure it out.

What log files do i need to check ?

This should be 3478 for STUN, not 3874.

well unfortunately the fault was in my post, not on my firewall
So i have actually opened 3478 in ISA both tcp and udp
And i get no stun errors.
Maybe my provider does not use stun ?
What options do i have if no stun ?

If your provider does not have stun you can use 3cx's.

stun.3cx.com
stun1.3cx.com

It does not make a difference as long as you use the same stun in all your phones and PBX.
