Icewarp sip trunk call issue with outgoing external call to Cucm MGCP Isdn Gateway(PSTN)

[M.Jakubowski]

Hello

This is my configuration

WebPhone CLIENT(iCEWARP)->SIP Server(Icewarp)->SIP Trunk_>CUCM 12.x->MGCP E1 Gateway->PSTN

I have created SIP Trunk and added to RouteGroup.

I have crated Route Parttition for 287 DDI/DN for testing.

Calls from PSTN to 287 DDI routed RG with SIP Trunk works perfectly.

Calls from/to  WebPhone with CUCM phones works perfectly.

Cals to PSTN(MGCP ISDN) from Webphone(IceWarp) fails.

PSTN Number (mobile) recives the call and answers it but don't hear nothing and the WebPhone still is allerting.

Hi,

Nothing is attached here.

To really troubleshoot this we are going to need

++ Cucm sdl logs ++

++ Gateway logs ++

debug mgcp packet

++ Sh run of mgcp gateway ++

++ Also the sip server logs ++

Please include call details...calling, called and time of call.
