W80DM and CUCM sip registration issue - kozlov - 10-11-2023 03:29 PM
Hello yealink community!
I have W80DM (fw
103.85.0.25) + 1 base W80D.
2 handsets - W78H and W56H.
Handsets successfully registered at base station, but i have problems with sip account registration.
I am using Cisco Callmanager 11.5 as sip server, all configuration were completed on it.
The main problem is that i am unable to register more than one handset at the same time.
Get "Register Failed". CUCM just response as 401 Unauthorized.
When i disable account at first dect phone, second registered successfully. So it is not an configuration issue.
I suppose that this problem exist because Yealink use the same local TCP|UDP port for registration.
Are there any ways to resolve this issue?

One possible reason for this issue could be that the Yealink W80DM is using the same local TCP/UDP port for registration, causing conflicts when multiple handsets try to register simultaneously.
