[cisco-voip] CAC Recommendation for a VoIP Network

[embeleco]

Hi.

I would like CAC recommendations for a VoIP network that consist of 6-10
(backbone sites) sites connected in a fully mesh topology (not
hub-and-spoke). Currently is a toll-by-pass solution consisting of Legacy
PBX connected to Cisco VoIP Gateways using ISDN-PRI/Q.SIG signaling. Also
customer has Gatekeepers in order to centralized dialplan. We are defining
which CAC (Call Admission Control) to use with the fully mesh topology.

We were thinking to use CAC at the gatekeeper but that will work best for
hub and spoke scenarios. It meas that gatekeepers will not know where the
call is going within the network... the other CAC solution that we are
considering is RSVP.


Any suggestions? Recommendations? Which CAC solution to consider?

Thanks in advanced.
