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.
