Register Poly VVX 150/250 to Webex Calling

rchaseling — Fri, 16 Aug 2024 10:28:46 GMT

I'm trying to register some Poly VVX 150/250 phones to a demo webex calling site we have setup. I have followed the process in this link

https://help.webex.com/en-us/article/njwkamr/Poly-and-Yealink-support-on-Webex-Calling#

to the letter but still won't register to Webex. I've tried both the polycom.broadcloud.eu and the polycom-eun.bcld.webex.com URLs but both the same. Got them plugged into my home network so no unusual security / firewall setup (running webex cscan tester gives good results from my network

Have the MAC address correctly entered into Webex Calling. How can I troubleshoot where this is going wrong without trying to get packet captures etc?

Hi @rchaseling ,

I haven't tried these device and it should work as it is supported. One statement I noticed in below document:

https://help.webex.com/en-us/article/qkwt4j/Supported-devices-for-Webex-Calling

Supported third-party devices

The use of third-party devices facilitate customer migrations to Webex Calling. The use of these devices on Webex Calling requires approval from your Cisco account manager to enable them for provisioning in Control Hub.

I have tried other third party devices but I never reached out to Account Manager to enable them for provisioning. May you can check with Account Manager if this can be the issue in your case.

mmm worth a shot i guess - the fact that you can select the exact phone model in webex makes me think it should work as is but I guess I better find out that answer. Will update

For me the poly needed an upgrade to the latest firmware version from Poly site

Hello, I too have wasted too much time with Poly's. I learned finally from the company (Acrisure) telephony support --->following the instructions for flashing from poly to WebEx will not work unless the phone is already in the Webex Control Hub. Once my company telephony support added it to control hub---registration worked with the flash instructions.

I had limited admin access to control hub

Good morning!
I've been searching for a few hours because I was having the same problem as you. After updating my VVX 450 and following the process indicated in the URL you sent, I was able to register it.

1. Update to the latest Polycom firmware (HOSTED). To do this, enter the phone's URL (with internet access) and use the Admin username.
2. Go to the Utilities tab and search for software upgrade.
3. Select Hosted and click Search. The latest software version will automatically appear. 3111-xxxxx-001.sip.ld (for VVX 150/250/350/450) build ID 6.4.7.4477
3. Create the phone in Control Hub and assign it to a user.
4. Follow the manual change procedure described in the following link: webex help

5. After a while, the phone reset and automatically uploaded the Webex settings.
