I am new to CUCM and CME.my company has already voip call manager and express setup. I  connected CME and CUCM   through h323 gateway and  dial peer to gateway and bindsrc command cme ip.and cucm and cme also connected through ICT TRUNK , i configured.my situation is that,i am able to make call cucm to cme but from cme to cucm call is not going, i am also able to make offnet call thru pstn gateway

[Hythim Ali El Hadad]

to call cucm from cme, you need voip dial-peer with destination-pattern [cucm range] and session-target [cucm.ip.add]

please show your conf here

Thanks for reply@hythamhadad

on the voice gateway, which is cme router

dial-peer voice 5000 voip

destination-pattern 500.

session-target ipv4;10.115.10.16(cucm ip)

dtmf-relay h245-alphanumeric

codec g711ulaw

no vad

voice-service voip

allow connections h323 to h323

allow connections h323 to sip

allow connections sip to h323

interface fa0/1.20

h323-gateway voip bind srcaddr 10.10.20.1

ON CALL MANAGER SIDE

H323 GATEWAY IS THERE WITH IP ADD 10.10.20.1

i have also done ICT trunk in cucm with cme 10.10.20.1

What tone are you hearing when you call CUCM phones from CME?  Can you attach a 'debug voip ccapi inout' from the gateway and run a test call.  Make sure your inbound CSS on your trunk in CUCM is applied and has access to the phones in CUCM you're trying to dial.

HTH,

Chris

only to confirm this line:

session-target ipv4;10.115.10.16(cucm ip)

I don't have a router now to confirm if the cli will accept ;

So confirm you do it as   ipv4:10.115.10.16

Hi,

Just to comment: You don't need ICT. The usage of H.323 gw in CallManager is the recommended way when integrating with CME. ICT is used for communication between CallManager clusters.

Now, you can also check if there's a codec mismatch.

Hope it helps, please rate if it does.

Regards,

Adrian.
