We have two G3Si switches located in in different sites. We have a DCS trunk over ISDN between these two nodes. We use one of the site as back up. On site A we have incoming DID from PSTN and on site B we have all ther users registered. We have same extension on Site A also for the back up purpose. We use to have the incoming calls transfered to the Site B when there was no user registered at Site A even though the same extension was also there in switch A. Now the incoming calls are send to the dead extension. Please someone help on this.

There is a setting on the dialplan or dialplan parameters screen (depending on release) that tells the switch to look up local extensions first, or UDP extensions first.

Yes there is the problem with that setting is that the way our switch are set that Site A and Site B have duplicate configuration the IP phones registers with Site B first if the Site B is down then it registers with Site A but the incoming DID are set at Site A. We want the DID to redirect it to Site B since the phone are registered at Site B. If I set the dialplan parameters to use UDP first it worls fine but when the Site B is down it still goes to site B where as we want it to dial the local extesion. The other proble is when the Site B is down and the users are registered at Site A they cannot dial local extesion as it tries to send it to Site B.
