Hello
I am not sure, how can it be telco dependant.
Consider the setup.
CCM -GW-H.323 GW -IP link -SoftSwitch
GW-H.323 Backup GW -IP link - Softswitch
If GW 's WAN link is down, backup GW can get the incoming DID from the
softswitch. Fail-over would then a matter of customer's routing
convergence.
Soft switch does not know, it is talking to GW primary or secondary
GW; it only knows that zone prefix is bound to H.323 end point which
is controlled by customer.
Welcome to the world of soft trunking.
