Yealink T48S configuration issue

[zorion]

Hi All,

Hoping someone can shed some light on this. I have added a Yealink T48S (software is upto date) to a a user. When I followed the instructions the settings got pushed out to the phone. I logged into the GUI and can see all the settings. Issue - just seems to be stuck on 'registering' and will not budge from that. The softphone app for the same user is working fine. SIP ALG is turned off on the router. Any suggestions would be welcome. Thanks.

I should have added, no issue on V18. I am having issue on V20.

Anybody?

Are you using a router phone or an SBC (Session Border Controller)?

Thats not the supportet way... You need to use an SBC if the phone is remote to the pbx.

No. I am going to have to if I want things to work smoothly. Thanks for asking.

Totally agree. Especially If one wants things to work smoothly. I was testing and since I had it working on version 18, I was a bit perplexed why it would not work on V20. Les highlighted 'unticking' the relevant box and it worked. Thanks for takiing time to comment.
