Hi Guys
I've been trying to configure my 3cx pbx v7 to connect to UK provider http://www.node4.co.uk
With SIP trunks settings as follow:
SIPLInk server:sip.node4.co.uk
Customer SIP server:213.249.254.XXX
Inbound number assing to SIP trunk: 08454130XXX
Outbound calls allowed to dial : 01,02 (all local calls up to 120s)
No registration is required neither user ID passwords etc
Everything is working fine with incoming calls. So If you dial 08454130XXX call is routed via node4 to my PBX in the office
then its routed internally to correct ext.
I can answer it have nice very good quality conversation
However we were unable to configure PBX to be able to make outgoing calls
As any attemps ebd up with error like this:
Called failed; Forbiden 403
Node4 people are saying that my public IP address 213.249.254.XXX is not included in VIA header of the SIP message
so their server refuses the connection as not legitimate
I have been trying to manipulate the headers to see if I can include our Public IP in the VIA header but so far no luck
Does anyone know how to configure the VIA header via 3cx so my ip address is inlcuded?
Btw I'm using generic SIP trunk template when setting up new VOIP gateway
I have installed wireshark to trace the call and I can see that my public IP address is not included in any of the messages sent to Node4
My PBX is behind Netgear WGR614 router which does NAT from 213.249.254.XXX to 192.168.0.X
My PBX IP is 192.168.0.8
Cheers
Shaun
