I have a common scenario where I have a centralized call manager (4.1(3)) at the headquarters and in the branchs routers that go in srts when the wan link goes down. When the link goes down the phones gets register with the router that is in srst mode, the only way for me to call to that phones from the central site is to dial de DID for that phone, in this scenario thus the AAR routes the call to the external number mask of the destination phone ?
Is there any way to dial de DN that is register in the router (srst) from one DN in the callanager, and the call manager reroutes the number to the pstn (with external number mask)
You can try setting the CCM line value "forward no coverage internal" to the analog SRST line at the remote site (sending calls to that line when the device is not registered) and set the router at the remote to send calls inbound on the analog to the local DN you prefer. This would work for as many DNs as you have analog lines into the router.
