Hello,

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???

It is not done adding interfaces, but dial-peers.

It is a normal configuration.

You should not ever use MGCP.

Hello,

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 ?

It is not done adding interfaces, but dial-peers.

It is a normal configuration.

You should not ever use MGCP.

Can you please give me a clue or example of what type of Dial-peer we require without binding the virtual interface via using h323???

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

preference 2

destination-pattern 1...

voice-class codec 1

session target ipv4:10.1.1.1

dtmf-relay h245-alphanumeric

!

dial-peer voice 102 voip

description CallManager Subscriber

preference 1

destination-pattern 1...

voice-class codec 1

session target ipv4:10.1.1.2

dtmf-relay h245-alphanumeric

!

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

Would you please upload the " sh run" from the GW.

The command is not need unless you have multiple interfaces.
