UCCM 7.0 WAN Failure options

Darren Sasso · ‎04-28-2009

Good Afternoon,

I have 2 UCCM's in 2 different countries where we are utilizing our WAN for dialing between sites. What options are available should i have a WAN failure and need to be routed out the PSTN. I do understand that AAR is used for CAC and not WAN failure, so i'm trying to determine what other options i have. I have built an intercluster trunk between the 2 UCCM's.

Thanks.

the only option is configuring the route pattern with the ICT in 1st place and then a PSTN GW making the appropriate DN transformations to call.

If ICT is unavailable it will use 2nd option which is the regular PSTN GW

Ok thanks. How will UCCM determine that the ICT is down and do you have any examples or know of any documents out there referencing this type of setup.

Thanks.
