[cisco-voip] CAC Recommendation for a VoIP Network

[Craig M Staffin]

if you are implementing call manager use the built in CAC it works well

Otherwise I thought gatekeeper could do CAC between sites as well as back 
to a central location

[cisco-voip] CAC Recommendation for a VoIP Network






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._______________________________________________
