UC540 Customer site choose between SIP and BRI for ephones

Unanswered Question

At a customer site I have installed an UC540 with one dualline isdn2 trunk and a SIP trunk configured. Incoming phonecalls are handled correctly. In my config outgoing phonecalls depend on the priority of the dial-peer (sip or pstn) whether the phonecals go out via SIP or pstn.

Is there a way to route one ephone through the SIP trunk and an other through ISDN? (CCA or CLI)

Kind regards,

Corlists, but not supported by CCA.The Cisco Press Voice Gateways and Gatekeepers book does a good job explaining it.

Thanks for the response.

Does this mean that in the next release of CME v8.1 where multiple SIP trunks are supported I have to configure outgoing calls with corlists similar as you discribed in your reply? Or will there be support for that in CCA?

Kind regards,

I did see that multiple SIP trunk configuration is on the roadmap for CCA. I don't have an exact date of implementation but it is on the list.

I will forward this thread to the PM.

Support for Multiple SIP Trunk Providers is planned for the Q2CY2011 release of CCA.
