I am having a hard time getting VoIP to work. I have a PBX using an IP trunk that is accessed over NAT.
I did port forwarding on UDP 5060 to my internal address. I can make calles but no audio. Whay is happening is that the RTP streams are assigned dynamically when the call is created. i can see the NAT translations outgoing but i don't think it is coming back in.
I tried doing
ip inspect name Incoming sip
ip inspect name Incoming tcp router-traffic
ip inspect name Incoming udp router-traffic
ip inspect name Incoming icmp router-traffic
and bounded it to my interface by:
ip inspect Incoming out
Still no audio but i can initiate out and also receive calls but can't talk to anyone :-(
I am having a NAT issue hard to resolve (at least I am still trying to figuring out).
Thanks in advance
