Problem with GK, CUCM and CUCME

[Luis Enrique Perez Trujillo]

Hi everyone.

I have a problem with call in CUCME to GK and CUCM.

The calls are made in CUCME to IP Phones in other office that registered at CUCM, the link between GK and CUCME is MPLS.

When try call to IP Phone in CUCME to IP Phone in CUCM the call not complete until after 2 attempts.

The number source is 532888 and the call destiny is 570777

I have logs about GK and CUCME and I follewed the message RAS found this errors:

I have separeted de CUCME and CUCM of GK and connected both directly via Dial-Peer voip with session target IPV4 and work fine.

Somebody any experience with this problem?

I hope your comments

[Chintan Gajjar]

Hi,

few questions:

is your CUCM is registerd with gk, if yes with what tech prefix?

i dont see any zone prefix for pattern 570777 in your gatekeeper configuration, so it may defualts to route the call to gateway which are regusterd with tech prefix 1#.

 can you please post full debug of Ras

VG#debug ras

aslo if you can post out put of below:

sh gateway (on voice gate which you are initiating calls)

sh gatekeeper endpoints (on gatekeepr)

above will help in understanding problem.

regards

Chintan

The prefix for 570777 its not define, I use the default prefix.

Attach the RAS debug.

Thanks so much...

Hi,

i see some logical configuration errors.

Aug  5 17:31:26.307: //162023/71FC44AD8499/H323/notify_ind: [cnum]/[oct]/[oct3a]= [570777]/[0x00]/[0x00]

look at the bold underlined above, you are initiating call from 10.44.194.65  whos h323 id is 

H323-ID: brasil-OficinaBoqueirao.domain.br

and destination for the call is chosen by gatekeeper is

10.44.227.33 whos h323 id 

 H323-ID: brasil-tda010.domain.br

 idealy call shoud go to call manager, but as there is no zone prefix configured for this patteren

and because of you are using default routing,  GK will route calls to endpoints registerd with techprefix 1# because of below config in you GK.

gw-type-prefix 1#* default-technology

gatekeeper is chosing random h323 gateway who is registerd with tech prefix 1#.

to solve this, i would recommend you to use zone prefix that routes calls to CUCM Gatekeeper controlled trunk.

what are your CUCM config? does it have trunk registered to GK? if yes can you please share the config?

regards

Chintan

[Luis Enrique Perez Trujillo]

Hi Chintan, I too see the errors and thanks for clarify my doubt.

When say zone prefix route the call to CUCM Gatekeeper, is necessary trunk between CUCM and GK?

The GK in CUCM is only registered, I dont remember created trunks for GK in CUCM

The configuration in CUCM for GK attach image.

[Chintan Gajjar]

Yes You would need that, GK can only route to devices which are registerd to it.

so have to have CUCM trunk registered to GK, so that you can route your calls.

under device --> trunk, do you see any h225 trunk there?

in your previous reply, when you provided "sh gatekeeper endpoints". i saw some endpoints registered to Gatekeeper as Voip Gateway. i thought those are trunks from CUCM.

are above not CUCM trunk?

Chintan

~please rate all useful post and mark them as correct if any

[Luis Enrique Perez Trujillo]

Hi Chintan, sorry the h225 was created already.

You have reason about trunk. Attach the screen h225 GK controlled in CUCM.

So, the configuration for the zone prefix is in GK with prefix for 570777?

Example:

zone prefix gatekeeper-name e164-prefix [blast | seq] [gw-priority priority gw-alias [gw-alias, ...]]

Where e164-prefix is 52.57....

Regards

[Chintan Gajjar]

all three trunks are from same CUCM cluster? or different ckuster?

what are the extesion range for cucm phone?

let me give example configuration thats suit your configuration

zone prefix gk-brasil.domian. 57.... gw-priority 10 TK-BRASIL-GATEKEEPER_2 

the above may not work because i dont have idea on your topology

but atlest you get example and configure in such way.

[Luis Enrique Perez Trujillo]

Hi Chintan the topology is the next:

The range in Bodega Brasil where is it GK and IP Phones registered in CUCM Mexico is 531XXX; the range in CUCME Boqueirao is 532XXX.

Is only one cluster for CUCM.

I review your recommendation and think is correct.

Best regards.

[Chintan Gajjar]

So why

you were dialing 570777, where is that registered?

regards

Chintan

[Luis Enrique Perez Trujillo]

Ok, when 570777, this DN are registered in CUCM cluster in Mexico.

The extension with 532XXX is a CUCME in Boqueriao that is one remote office to CUCM Mexico, the GK is are in Brasil in other region different to Boqueirao.

I revised the configuration in GK and find this line command:

zone prefix gk-brasil.domain.br 532... gw-priority 0 brasil-OficinaBoqueirao.domain.br

[Chintan Gajjar · Accepted solution]

I realized that , there are lot of misconfiguration are there in place.

1. gw-priority 0 : the priority of gateway 0 in your zone prefix almost blocks that route, so never use unless you want to block gatekeeper to use that route, use priority 10 instead.

2. h225 trunk of CUCM are registered to gateway using tech-prefix 1#, ideally tech prefix differntiates goupr of similar kind of device. 

so ideally people use different tech-prefix on Voice Gateways than CUCM.

we use 1# for Voice gateways to register with GK, and 2# for CUCM trunks

3. the zones are not properly defined. if we look at CUCM trunk configuration,CUCM Trunk is configured to register with GK on zone gk-brasil.coppel.br, but as there is no such zone defined in gatekeeper CUCM trunk will register with first configured zone in gatekeeper.

so if you want to correct most of it, please do this.

1) define a zone for CUCM in gatekeeper

zone local gk-brasil.coppel.br domain.br

2) remove gw-priority 0 from zone prefix in your gatekeeper, and put it to 10.

i see lot of zone prefix cinfigured with gw-priority 0, whichever ones you are actively using, please remove 0 and put it to some higher value preferably 10.

0 means block that route.

3) configure CUCM trunk:

in your CUCM trunk, in the section of Gatekeeper information

insted of prefix 1# use 2# ore some different values.

and reset the trunk. resetting trunk will drop all the active calls so better to do it in off hours.

4) this is to solve your routing to CUCM problem, considering 531.. as extension range of cucm, add below prefix:

zone prefix gk-brasil.coppel.br 531... gw-priority 10 <H323-ID-CUCM Trunk>

but again, 570777 will still not get routed to cucm, if you have to add such pattern in gatekeeper.

regards

Chintan

~please rate all helpful information and mark correct if any

[Luis Enrique Perez Trujillo]

Chintan, for your points I configured in the GK

gatekeeper

zone local gk-brasil.domain.br domain.br 10.44.209.1 //replace coppel for domain

!

Change the priority for zone prefix to 10 and trunk

zone prefix gk-brasil.coppel.br 531... gw-priority 10 TK-BRASIL-GATEKEEPER

If change the prefinx in CUCM Information GK i need the change te configuration in the command gw-type-prefix 1#* default-technology?

Regards and thanks for you help.

[Chintan Gajjar]

if you want to default route all the calls to cucm then do it, otherwise its ok to keep it.

did you check if you are able to dial the number now?

regards

chintan

[Luis Enrique Perez Trujillo]

Chintan, a couple hours I will do the change.

I will you notify the results when dial the number.

Regards
