ATA in SRST with Shared Line

Unanswered Question


I have an IP phone and ATA that share the same DN (shared line appearance - SLA). Do you know if SLA can be supported in SRST mode as well?

I have CM 4.2 and SRST 3.3 on Cisco 2821.

ATA is running SCCP image.

When we fail the router into SRST mode both, the phone and the ATA, register but the ATA gets a bogus DN and doesn't even provide dial tone to the analog phone. The ATA is listed as registered on the SRST router but is not functional.

Thank you,
