Notifying PBX if Voip calls can't be completed from WAN

I have 10 2621XMs each connected directly to G3 PBXs. They supply VOIP call lines to the PBX via a direct T1 (NM-HDV-1T1-24). However, when the direct T1 is up between the PBX and the CISCO router, how do I tell the PBX that VOIP calls can't be completed? This, in it's simplest form, would be due to a Frame outage on the WAN side, or perhaps internal call issues in the cloud. Using basic configs, the PBX will only know it when the direct connect T1 is down not the WAN T1 on the other side of the router. Is there any proven ways to track other interfaces or routing and convey that to the voice-ports by seizing the unused ports or taking down the direct connect T1?

Perfect. Just what I needed. Thanks.

I have a similar problem to this, but instead of monitoring the locally connected LAN/WAN interfaces,to determince when to Busyout, I need to monitor whether the remote VOIP gateway is down, to decide whether to re-route the call back to the PBX. At the moment when I test calls from local PBX to remote PBX, via a pair of local and remote VOIP gateways, the call does not automatically re-route via PBX ISDN, when the remote VOIP gateway is down.
