W80DM and CUCM sip registration issue
Hello yealink community!
I have W80DM (fw + 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?
