Paging with Communications Manager Express


A nice feature in CUCME is you can do voice broadcasting (paging) without any third party integration like Berbee. Here is a tutorial on how we do it:

telephony-service
max-dn 30 no-reg both

! Paging group configuration
ephone-dn 21
number 2021
paging ip 239.1.1.21 port 2000

ephone-dn 22
number 2022
paging ip 239.1.1.22 port 2000

ephone-dn 23
number 2022
paging ip 239.1.1.22 port 2000
paging group 21,22 ! Combined Group Paging

! Assign phones to paging group
ephone 1
paging-dn 21

ephone 2
paging-dn 21

ephone 3
paging-dn 22

ephone 4
paging-dn 22

When you make a call to paging group extension 2021, ephone 1 and ephone 2 will ring and auto-answer with speaker on. Ext 2022 is similar, ephone 3 and 4 will ring and auto-answer when somebody dials 2022. When you call the combined group paging number 2023, all 4 phones in the paging group 21 and 22 will rings, so the nested structure provides some flexibilty for you when you configure paging.
