Hi,
I trying to reduce the amount of dial-peer that send calls to the cucm from the itsp. I currently have 2 dial-peers pointing to 2 different call managers.
I tried to change the ip with dns.
OLD Dial-peer
===========
dial-peer voice 50 voip
description "TO PRIMARY Call-Manager"
destination-pattern 10001
session protocol sipv2
session target ipv4:192.168.1.10
voice-class codec 16
dtmf-relay rtp-nte
no vad
dial-peer voice 51 voip
description "TO SECONDARY Call-Manager"
destination-pattern 10001
preference 1
session protocol sipv2
session target ipv4:192.168.1.20
voice-class codec 16
dtmf-relay rtp-nte
no vad
I changed it to:
dial-peer voice 50 voip
description "TO Call-Manager's"
destination-pattern 10001
session protocol sipv2
session target dns:CUCM.example.com
voice-class codec 16
dtmf-relay rtp-nte
no vad
I can ping the CUCM.example.com from the gateway and in the dns server the below is registered:
NAME Port Weight Priorty IP
-------------///////////////////////////---------------///////////--------------///////-------------////////////-----------------------------------------------//////
CUCM01.example.com----------->5060------------->10--------------->50------------------>192.168.1.10
CUCM02.example.com----------->5060------------->10--------------->50------------------>192.168.1.20
CUCM03.example.com----------->5060------------->10--------------->50----------------- >192.168.1.30
CUCM04.example.com----------->5060------------->10--------------->50------------------>192.168.1.40
But when I try it invalid number and CUCM is not depended on DNS.
ITSP ------->CUBE ------------>SIP-TRUNK-------->CUCM
Is there anything I'm missing?
Thanks
