Hello,I have 28xx and 5350 routers with E1 cards, acting as Voice Gateways, converting from SIP to Q931.(124-16b IOS).I have the following problem:1) Inbound call on the Q931 interface (SETUP)2) SIP INVITE sent by VGW to customer SIP Endpoint3) En...
Hello,I have a 2851 router with E1 interface connected to an ISDN network provider and a BRI interface connected to a Sony PCSA-B384S Video Conferencing unit.I want the VC unit to be able to dial via the BRI circuits and "break out" through the E1 (i...
