Hi Folks

I am very new to Cisco CM and looking to see the best way to twin an external bell to a handset, I felt I was going down a bit of a rabbithole when looking into the "mobility" settings.

I basically just want it so when someone rings this one extension the external SIP bell sounds too. Bell is already registered etc, just the twinning bit I am struggling with.

Any advice would be most welcome

Thanks

I think you can just build the ATA and add the IP phone's DN to ATA Line 1.

So I have tried that however I get "Partial registered" on my bell and it doesn't ring.

The site is far away and I cannot get into the SIP Bells admin page due to the network config so I am fairly limited.

Is hunt group the only other option?

Avaya just had an "enable twinning" mode! was so easy

An ATA is an analog convertor device. you cant plug in a SIP device to it. So you'll need an analog Bell to connect to the ATA.

Are you trying to register the third party SIP device (bell in this case) directly to call manager then? If it shows partial registration its probably a configuration setting that needs to be adjusted, either in the SIP device config or the call manager side config, or both.
You will need to have access to the the SIP device config or I dont see how else you'll be able to troubleshoot this.

I am aware what an ATA is, been working on PBX systems for 15 years.

The bell itself is SIP I am not using an ATA nor have I said I was.

I have it resolved anyway.
