We have both sccp and sip phones with shared lines. When on SRST only the sccp shared line will ring for an inbound call but not the sip shared line. Is there a way to make this work or is this not supported?

At a bare minimum, you need to make sure your gateway is configured to function as a SIP Registrar Server for the phones. You can achieve this under the 'voice service voip' section.
>enable
#conf t
#(conf) voice service voip
#(conf-voi-srv-voip) sip
#(conf-voi-srv-voip-sip) registrar server [expires [max sec] [min sec]]
If you already have this, then throw up your config so we can break it down and troubleshoot.

Hi Manish.
Did you ever get to the bottom of this? I have the same problem with a 9971 and a 7925. In SRST they both register with the shared DN, but if you call the DN, one time the 9971 will only alert and the next time only the 7925 will alert?

Hi Tim,
As per the following
http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucme/admin/configuration/guide/cmeadm/cmebasic.html#pgfId-1081127
To configure a mixed shared line between Cisco Unified SIP IP and Cisco Unified SCCP IP phones, perform the following steps.

Thanks Manish.
I think I am safe in assuming I need to be using CME as SRST and not CallManager fallback like I am now for this to work?
