[cisco-voip] AAR -- options

[Daniel Rodriguez]

Hope I understood your questions correctly. Enjoy the weekend.

What if:


1.      you don't have PSTN lines available?  ie> I have a VGW setup in a different town just for Toll bypass (but it only has 4 FXO ports).  if the fifth call is sent there then what?  how can I fix this.  AAR would be nice so that I can prepend the 91 to the number, but how do I work that?
The AAR Group in CCM is responsible for your prefixing needs. If you have two different sites, one requiring *9 and the other just 9 for outbound calls, use your AAR groups to accomplish this. The call will be routed based on the AAR group of the calling party and the AAR destination mask of the called party.

If you only have 4 FXO ports for outbound calls to the PSTN, and you have 4 active calls, add another gateway to your route group(s). If CCM is attempting to reroute a call to the PSTN, but no gateways are available, then your route list will be exhausted (assuming its matching a RP).

or

2. you WAN goes completely down?  Remote site will be fine with SRST.  if configured correctly it will prepend all the extensions with 91xxx-xxx and through dial peers I can prepend the 1 for toll bypass, but what about the HQ site?

Not sure what you're asking here. Do you want to know how your HQ phones will be able to reach your remote site phones?

Just trying to come up with some solutions.

Thanks

Scott
