Hi hadelmahmoud,

CallManager will not redirect the call to GW2 in case E1 of GW1 cannot route the call to PBX.

To do this, please configure in GW1 a VoIP dial peer to reach PBX numbers with a high preference value (so that it is less preferred) and a session target pointing towards GW2. Then in GW1 configure:

voice service voip

allow-connections h323 to h323

Hope this may help you.

Best regards,

- Adrián.
