I have 3 sites connected to one main site (all using cme).Main site has 12 FXO Ports. Now i want to connect that main site with our HQ CUCM. Which protocol do i need to use? and why any idea???
Solved! Go to Solution.
You have not mentioned any details with regards to main site. Are you connecting another CME from main site or a Voice GW?
If I presume a Voice GW at main site, you can utilize MGCP if you would like to have complete control from CUCM (HQ).
Main site is running CME itself. sO it has already one h323 interface. I dont think so that i can add two h323 interaces in one router one for local phones and other for CUCM ?
Something like this should work:
voice class codec 1
codec preference 1 g711ulaw
codec preference 2 g711alaw
codec preference 3 g729r8
codec preference 4 g729br8
dial-peer voice 101 voip
description CallManager Publisher
voice-class codec 1
session target ipv4:10.1.1.1
dial-peer voice 102 voip
description CallManager Subscriber
voice-class codec 1
session target ipv4:10.1.1.2
It assmumes that you have two CUCM servers - a Publisher with IP address 10.1.1.1, a Subscriber 10.1.1.2 - and that the CallManager extensions are four digits starting with a 1.
thnx v much for your info.
I just googled and came to know that in order to h323 protocol on gateway, we dont need the h323-gateway voip interface command to register h323 gateways to Call Manager, only needed the h323-gateway source address command.
But i am gettting below error whenever i put h323-gateway voip bind srcaddr X.X.X.X command under loopback interface.
Bind IP Address configured. Please remove before reconfiguring

interface Loopback10 ( here i want to put h323 command in order to get connected with cucm)

ip source-address 10.5.83.254 port 2000

no h323-gateway voip bind srcaddr 10.5.83.254
h323-gateway voip bind srcaddr 172.16.250.150
this command enable you to source h323 traffic with a specific ip add
It help in defining ur security policy to this specific IP
from my understanding, you need to use the same cme as h323 gw in many cucms
so why you don't use the same ip add as h323 gw in all the cucms
