Routing incoming call From "Master" Bridge to "Slave"

[Laurent Filippi]

Hi

I'm expecting some trouble with a bridge configuration : i have the following instalation (Simplified)
HardPhone (100) <=> 3cx Slave Bridge <=> 3Cx Master Bridge <=> VOIP Provider (I Have no VOIP Provider for slave Bridge)

I was able to route outgoing call from a My Slave Extension to a VOIP provider defined on the master bridge.
HardPhone (100) => 3cx Slave Bridge => 3Cx Master Bridge => VOIP Provider ( Works Well)

by i found no solution to route incoming call coming from my VOIP provider to an extension attached to the slave bridge.
HardPhone (100) <= 3cx Slave Bridge <= 3Cx Master Bridge <= VOIP Provider :-(

The point is : My customer want to have all the VOIP connexion in a "central" point and so the master 3CX will have to act like a "HUB".
Any idea is welcome.

Regards
Laurent
