Integrating CME 8.6 with CUCM

[ivan aguilar]

Hi!

I am trying to integrate a CME 8.6 with CUCM via MacroLan, i introduce this commands in router to do this:

dial-peer voice 1234 voip

preference 1

destination-pattern 1...

session target ipv4: <IP del CUCM>

dtmf-relay h245-alphanumeric

codec g711ulaw

no vad

Interface gigaethernet0/0.10

h323-gateway voip interface

h323-gateway voip bind srcaddr <ip del CME>

When I place a call to extension in CUCM , call goes in dial-peer 1234 but drop calls.

Do I need to modify or add anything else or is a Macrolan problem, so Operator must to do it?

regards!!

Hi Ivan

see the region relationship between the the ip phone and the gateway(trunk) going to the CME, as you have set it as g711 on the dial-peer.

get me a set of ccm traces along with calling party called party information going towards to the CME with detailed traces and enable gateway trace.

Hope this helps

Hi,

Finally I resolved the connectivity problem, actually i ping from CME to CUCM, but stills can not place call between the two headquarters.

step 1, I create in my side one dial-peer (see in the last post) and a h323-gateway voip interface

step 2, in the CUCM I have created one route pattern to my new extension.

Do I must to create another dial-peer o h323 in the CUCM gateway?, which should be the step 3?

Thanks!

You need to configure the CME as an H323 GW using the IP to which you're binding the signaling.

What is the GW configured like in CUCM, how many sig digits did you select and does the calling search space have access to partition assigned to the DN you are calling?

Is the GW showing up in CUCM with the IP address and registration UNKNOWN?

Actually from CUCM still can not phone my extension in the CME, so need to add anything else, or a h323 gateway o i dont know.

regards.

[Chris Deren]

Can you post "sh run" and "debug voice dialpeeer"?

[Jaime Valencia]

So far what do you have configured on both sides???

one change, in cucm dial-peer voice 1234 the destinattion-pattern is 4...

still place a call by pstn and drop the call

Calling Party Number i = 0x0081, '93XXXXXX'

                Plan:Unknown, Type:Unknown

        Called Party Number i = 0x80, '4110'

                Plan:Unknown, Type:Unknown

Jul 19 15:53:07.122: ISDN Se0/0/0:15 Q931: RX <- CALL_PROC pd = 8  callref = 0x8530

        Channel ID i = 0xA9839E

                Exclusive, Channel 30

Jul 19 15:53:07.498: ISDN Se0/0/0:15 Q931: RX <- PROGRESS pd = 8  callref = 0x8530

thanks!!

This should E1-ISDN call not IP call between systems.

Where are you calling from to? Please post you entire config.

Vi

I am making a test from CUCM to CME and fails because route the call by the PSTN

Hi,

I have added a H323 Gw in the CUCM with the IP 192.168.6.9 (CME IP), but when I try to place a call from a CME extension to a CUCM extension, drop the call.

What I need to add to my configuration in order to run this integration???

Thanks!!

On CME you need to have a voip dial-peer that points to the IP address of the CUCM, and matches the destination pattern of CUCM DNs.

On CUCM you need to ensure the H323 GW is configured with proper CSS which can route the call to the partition of the phone DN and the significant digits on the GW configuration is set properly.

That's about it.

Hi,

Finally it was resolved, the problem was with the CSS_inbound of the Gw H323.

After change it, already is working properly.

Thanks, and regards!!!
