SIP trunk to Cube to IP PBX

[Mark Verwey]

I am attempting to configure a 2951 with a Cube license to go between an IP phone system (Avaya IPO) and the SIP provider.  When I call in, I see call info coming into the CUBE, however it never goes beyond there.  When I attempt to make an outbound call, it never hits the CUBE.  Any suggestions?

Hello Mark,

Can you post part of the configuration, ie the dial-peers that describe the 4 legs of SIP Signalling (incoming/outgoing)?

Ideally you should have 2 call legs with

WAN Dial-Peer Configuration:

Inbound Dial-Peer for call legs from SP to CUBE 

Outbound Dial-Peer for call legs from CUBE to SP

LAN Dial-Peer Configuration:

Inbound Dial-Peer for call legs from PBX to CUBE 

Outbound Dial-Peer for call legs from PBX to CUCM

Let us know,

George

Do you have both dial-peers configured? 

You have two call legs, so you will need two dial-peers for each direction (four total)

Incoming call: PSNT --(1)--> CUBE --(2)--> PBX
Outgoing call: PBX --(3)--> CUBE --(4)-->PSTN

Make you have all of them ready and try again, if you keep having troubles post the following debugs:

debug ccsip messages

debug ccsip events

debug isdn q931

Regards.
