Has anyone ever implemented an NEC SV9300 with SIP trunking to a Rauland Telecenter U-SIP controller with a Brekeke SIP server in the middle? The Telecenter is running and talking to end points -- trying to figure out how to configure the SV9300 SIP trunk to the Brekeke and the programming in Brekeke to have it flow through to Telecenter SIP station.
