WAN VoIP redundant links

[sstatho]

Hello,

There is an installation of a callmanager on a site and there is fast link (Aironet 11Mbit) with another site with 20 IP Phones. Link load is small (less than 7-8 calls). We use G711, as b/w is not a problem.

We have a BRI backup link (DDR configured) in order to have connectivity when aironet link fails. BRI b/w is not enough so we have to use G729. How should we configure CCM in order to use G711 normally and G729 when the backup BRI WAN link is up?

Thanks,

Stathis
