NBX inbound calls rejected with SIP Trunking

We have a V3001R V6.5.22 running in Native SIP mode with a SIP trunk provider (Orcon, in New Zealand).



We can make outbound calls, but all inbound calls are rejected. Our firewalls shows the inbound calls arriving.



Firewall logs:

UTC 11/13/2009 22:13:51.672 Debug VOIP SIP Response 10.189.190.190, 5060, X5:V190 10.20.25.69, 5060, X1 SIP INVITE (404 Not Found) (94443686@10.20.25.69 to 94767893@10.189.190.190:5060)

2 UTC 11/13/2009 22:13:51.608 Debug VOIP VoIP 10.189.190.190:5060 (SIP) 94767893@10.189.190.190:5060 Endpoint added

3 UTC 11/13/2009 22:13:51.608 Debug VOIP VoIP 10.189.190.190:5060 (SIP) 94767893@10.189.190.190:5060 Endpoint removed



What changes do I need in the dial plan to get inbound calling to work?

Ideally, I'd like to send inbound calls to our main Auto Attendant ext "500" during open hours and to an after hours auto attendant "505" when closed.

Re: NBX inbound calls rejected with SIP Trunking

Create another pretranslator that will take the number 94767893 and replace it with 500. Make sure in the pretranslator list on netset you add the SIP trusted endpoint.

That should do it !

I have done so already, and it does not work.

Re: NBX inbound calls rejected with SIP Trunking

..and in the SIP Inbound pretranslator table you have the SIP device?? that should do it.. not sure why.

Look at the NBossLog after making a call and look for a "router" error.. that should help troubleshoot.

hi.

Just a note that NBX does not support direct connection to SIP trunk provider.. SIP trunking to another NBX or to a VCX.

with that said, I did notice in your pretranslator that the number coming in is 9476893 and you have in the pretranslator 9476891.

Re: NBX inbound calls rejected with SIP Trunking

Yes, 94767891 is out main number and that is temp diverted to our analogue fax line. The call step line is 94767893 and I hand amended my posting (but only amended 1 line of it by mistake...) my actual dialplan is correct.



 



The SIP endpoint (ext 755 in our case) is using the correct pretranslator (as set in Netset)



You said:



"NBX doesn't support direct connection to a SIP trunk provider..."



 



I hope that's not the case!
