Cisco MX300 dual registration: SIP & H323

[hans.mahadea]

Hello,

Can anyone confirm if it is possible to have an MX300 register both using SIP and H323 at the same time?

Thanks,
Hans

Can't see why not considering it's using a C20 type codec (don't know if the newer ones use SX20 instead), so it's just like any other C-series as far as I know. Even the web gui screenshot in the admin guide shows it as being registered to both.

On a VCS-C yes you can.

If you use CUCM as the provisionning entity it's not possible see below.

Provisioning support

When using CUCM provisioning, the endpoint cannot register to a VCS (SIP or H323) at the same time. This use-case is not supported by Cisco. When CUCM provisioning is active, H323 mode is disabled. Cisco recommends TelePresence customers to migrate from H323 to SIP.

Jean-Christophe,

You are absolutely right that you should not mix UCM and VCS registrations like that in a production environment.

That being said, it seems to work on older endpoint software; I for example keep some of my TC5.1 endpoints registered on SIP to an UCM and on H.323 to a VCS-C. This is for lab / test use though, and I would never do it like that in production.
