Point to point Cisco 2620 both with E1 MFT running QSIG to Nortel Meridian Option 11 both ends.
When the Leased Line fails I want the PABX to "see" that it cannot complete the call over the router link and it will then use the PSTN.
Can I get the router to busy out all local b-channels when the leased line fails, or is there another recommended solution for this?
