I have a UC560, CME version 8.1 with 20 phones, some phones are SPA504 (7.4.8a)
and others are SPA525G2 (7.4.9a)
Here it is the paging-dn config:
number 101 no-reg primary
name Office Page
paging ip 220.127.116.11 port 2000
The strange behavior I get is that not all phones are receiving the paging and this occur randomly between phones, sometimes one phone works fine and sometimes it doesn't.
Thanks for any help
