Yealink T42S: Multiple extensions

[oguruma]

I am trying to set up my T42s with a second extension. When I try to provision it via the 3CX UI, I get the message "...belongs to MAC XXX choose another phone/MAC.

Phone and 3CX server are both on LAN.

I am assuming I need to enable the other "accounts" via the Yealink UI, but when I populate the fields in the Yealink UI with what makes the most sense to me (Port 5062/The register name of the phone, and the username and password for the extenion) I get "register failed" on the Yealink UI.

I successfully provisioned Line1 with a different extension and Port (5060).

I'm afraid you can do this only manually or seriously modify the template. Depends how many phones you want to provision.
Long time ago I managed to provision both ports of Cisco SPA2102, which is theoretically the same task.

Hi oguruma,
Maybe the link below will help you.
https://www.3cx.com/docs/hot-desking/#h.7p7377nvt9d5

To use hot desking a Pro or Enterprise licence key is required.

It's only two phones that I want to set up. When you say "you can do this only manually" are you meaning I can only do it through the Yealink UI... or???

When I register one line (account) in the Yealink UI, the first one is successful. Every other one "register fails".

yes, exactly -- configure second account manually through UI of the phone

Interesting. That seems to be what I am having trouble doing... The first line (account) registers successfully, but I get "register failed" for the rest of the lines...

I don't have an Yealink phone at my disposal right now to make screenshots, but there is really nothing special about registering a second account -- you enable the account in the user interface of the phone, enter user ID, authentication ID (could be different from the user ID in 3CX v15.5), password and SIP server -- the local address of the PBX. The rest settings remain default.
