We plan to use bandwidth on demand(BOD) over BRI Back-up circuits to bolster up exsting frame relay circuits for delivering IP vidoconferencing to small remote wan sites in a Single Zone WAN videoconferencing model installation.
Remote site will have Cisco 7960 IP phones with IPSoftphone and Microsoft Netmeeting Integration.
Central Site will have similar Clients plus 3510 MCU and 3525 PRI PSTN(H323) Gateway.
On detection of H.261 the ISDN circuts will either be used to Multi-link with frame or be dedicated for H.261 use between netmeeting clients(with Cisco IP Softphone integration). Voice will be G729 between Existing 7960 Cisco IP phones or G728 if call is breaking out/in via central IP/VC352x gateway and could stay on frame.
Frame realy already implemented for QOS and used for VOIP in large Callmanager Installation.
BRI capable of 64 or 128k
Existing Frame Speed to 256k
Initial Quality required to be similar to: 128k h.323 ISDN Business Quality.
Any Experiances, comments or Guidence welcome as Videoconference design guide does not discuss use of BOD or integration with Callmanager Installation.
