Dialogic: 192.168.0.19
Everything is configured and ready to go
Outbound Calls go through all the way from the Communicator but rejects at the Dialogic end.
While sniffing Packets at the Dialogic side all UDP SIP/RTP Packets are received at port: 0
Which doesnt make sense as it should be received in media streaming range 60000/64000 which is configured from both ends Mediation and Dialogic.
Below is the event log from the Communicator Client.
