Integration between CCM and UC520

Hi All,

We need to establish a connection between CCm release 4.0 and UC 520.

configuration from CCM side: we configure a H323 gateway to go directly to UC520

configuration from UC side: it's a simple dial peer

dial-peer voice 1000 voip
destination-pattern 6567
session protocol sipv2
session target ipv4:10.0.100.90
dtmf-relay h245-alphanumeric
!

we can call normally from CM to UC, but from UC to CM the call failed.

Could you help on this please.

Regards,

Mohamed Sherif

Howdy,

Can you verify the CSS on the h323 gateway is configured?

Hi Kevin,

We don't have any calling search space configured in the call manager, current configuration is none.

Thanks

Re: Integration between CCM and UC520

Make sure you have the command:

h323-gateway voip bind sr

That IP needs to match what you configured in CUCM under H323 GW.

EDIT: just as an FYI this is NOT supported.

Q. Can the Cisco Unified Communications 500 Series be networked with Cisco Unified
CME or Cisco Unified Communications Manager?
A. The Cisco Unified Communications 500 Series can be networked with an integrated services
router-based Cisco Unified CME, but the Cisco Unified Communications 500 Series does not
work with Cisco Unified Communications Manager.

Re: Integration between CCM and UC520

Hi javalenc

This command is there

h323-gateway voip bind srcaddr 10.1.2.1

10.1.2.1 is the same IP configured under H323 GW

Thanks

Re: Integration between CCM and UC520

It seems you are trying to integrate via the Voice gateway running SIP towards the UC520.

You will need to create similar dial-peer pointing to CM from the voice gateway and make sure this gateway has the following commands:

!

voice services voip

allow-connections h323 to h323
allow-connections h323 to sip
allow-connections sip to h323
allow-connections sip to sip

!
gateway

!

interface

h323-gateway voip interface

h323-gateway voip bind srcaddr

!

Ensure this IP address is added as H.323 gateway in CCM and have incoming CSS set (or if u are not using PT/CSS - none)
