I have confirmed its working on the LAN. So it seems I have an issue with Zone based firewall on the ISR transmitting the call across a WAN

I have opened up TCP & UDP all ports to the Private IP on the ISR (The Lan interface) which is what SIP listens on.

 

When i try and connect, I can register fine from the internet on my mobile SIP client. However, I cannot make a call. Nothing happens.

This works perfectly fine when on the LAN only.

 

I suspected RTP/SIP port issues but ive opened it ALL up, even turned off the Zone Based firewall. Still the same issue

I see this in SIP debug from the WAN

Hello
i think its network transport issue.
You can't sent invite until transport layer will acces.
Check:
sip
session transport tcp
or maybe your session transport udp
You can use debug ccsip all in maintanance window for show all info during a call.

What interface on ISR has "192.168.0.254" IP ? Enable the following and share the logs in a text file -

debug ccsip message
debug ccsip error
debug ccsip info
debug voice ccapi inout

Hello, I should clarify this router is a Cisco 3945 on 15.6 not an ISR. I have also tried  Version 15.2(3)T3

 

I'm also using NAT NVI.

 

I have placed those debugs on, but I dont get alot of outut.

 

Gig0/0 is the WAN interface, and obtains its IP via DHCP

Gig0/1 is in a Bridge group, with VLAN1. VLAN1 has ip address 192.168.0.254

It is an ISR - Integrated Services Router. Take the log again and in buffer with appropriate buffer space. Not on term mon. I don't see any call in these logs.
