Valcom 801a ATA integrate with CUCM 12.5 for paging

kevranke — Wed, 16 Oct 2024 18:52:43 GMT

Hello,

I have a Valcom 801a that I need to integrate with Call Manager 12.5 for paging in a building. I configured the ATA to the best of my ability with the Valcom software but the device shows as "rejected" in Call Manager.

Has anyone set one of these up that could point me in a good direction to go next?

Thanks so much!

-Kevin

Two suggestions if you don’t get a direct answer:

There are plenty of examples for registering 3rd-party SIP devices to CUCM. Reviewing these may offer clues. Example: https://netcraftsmen.com/sip-endpoints-in-cisco-cucm-x-lite-as-an-example/
Valcom works with Cisco often. You may want to ask their support team for guidance

The Valcom 801a must be configured as a third-party SIP device on CUCM, not as an ATA. For instructions on registering a third-party phone on CUCM, you can find several articles online, and the link shared by @Jonathan Schulenberg is highly recommended.

You will also need to configure some settings on the Valcom 801a web page to register the device. For detailed guidance on this, you need to contact the Valcom support team.

Thank you! I worked through this link, too bad the images were stripped. With your article and some google fu, I got the ATA registered as a 3rd party SIP device and working.

Fun Fact: The device needs to have a line assigned before CUCM will accept it.

Thanks!
