Incoming and Outgoing Call Issue

Hi,

 

I tried to deplu CUCM>VCS>VCS Express. but both incoming and outgoing calls are not working.

 

the following is search history for two calls one came from external endpoint to 1800@External_Domain.com (Error: Resource unavailable - No route for bandwidth calculation)

and another one from Cisco IP phone 1800@External_Domain.com (Error: Temporarily Not Available)

It looks like the neighbor

It looks like the neighbor zones to CUCM doesnt exist. Have you followed the guide:  http://www.cisco.com/c/dam/en/us/td/docs/telepresence/infrastructure/vcs/config_guide/Cisco_VCS_Cisco_Unified_Communications_Manager_Deployment_Guide_CUCM_8_9_and_X7-2.pdf?

it is existbecause I am

it is exist

because I am making calls from CUCM to VCS and calls reach to VCS express. I have used the guide.

Could you share a screenshot

Could you share a screenshot from the search rules page? If you are using transforms for manipulating called number, please provide that as well.

I do not have access right

I do not have access right now, but I can tell you the configuration

 

For calls coming from outside to CUCM. I am dialing like this:

1800@Real IP address

when I checked the incoming calls I found the address only 1800, so I created a transform to to transfer from 18(..) to 18\1@domain.com

 

then a search rule .*@domain.com to (traversal zone > VCS Control) the same search rule it is created in VCS control > neighbor zone (CUCM)

What version of UCM are you

What version of UCM are you using? Have you set the Clusterwide FQDN to the domain that you specify in VCS? If not the calls wont work.

Also, i dont think the call is hitting a CUCM neighbor zone from the debug you posted initially. 

Its going to VCS Express after it matches the last rule which I think in your case is to route to VCS Expressway.

I have CUCM 10FQDN is

I have CUCM 10

FQDN is configured in CUCM.

The first debug is related to call coming from outside to CUCM, I take the output from VCS-Express. It is showing that call is forwarded to VCS Control

it looks from the information

it looks from the information that you may need to relook at your transforms and search rules

Could you please give me more

Could you please give me more details,

 

Did you read the configuration that I added in the previous post:

 

For calls coming from outside to CUCM. I am dialing like this:

1800@Real IP address

when I checked the incoming calls I found the address only 1800, so I created a transform to to transfer from 18(..) to 18\1@domain.com

 

then a search rule .*@domain.com to (traversal zone > VCS Control) the same search rule it is created in VCS control > neighbor zone (CUCM)

 

any thing wrong here?

I meant to add a little more

I meant to add a little more to the post. What would be needed is to see all the search rules their order/priority, transforms, pipes/links and zones in order to determine where the issue is. Maybe even the dial plan also. If all that is correct then we'll look at the CUCM, but it doesnt look like the call is making it that far along.

Hi,I was thinking about this

Hi,

I was thinking about this portion:

Gatekeeper (1)
                                    Address: 172.25.9.210:52242
                                    Alias (1)
                                        Type: H323Id
                                        Origin: Unknown
                                        Value: 1800@External_Domain_com

 

The previous IP Address (gatekeeper) is my VCS-C but the phones are registered to CUCM and no phones are registered on VCS-C

What format are you dialing

What format are you dialing from VCS to reach CUCM? The call flow should be VCS <>CUCM. Calls will only traverse through VCS Express when it needs to go out of your organization. So for a call coming in from the internet, the call flow will be VCS Express <> VCS <> CUCM. 

What exactly are you dialing to get to CUCM? Are you dialing extn@CUCMDomain or extn@CUCMIP? I would focus on getting calling between VCS and CUCM working before throwing VCS Express into the mix.

I am dialing from internet

I am dialing from internet (another system) Exten@Real IP address

Real IP address>>VCS Express.

from VCS Express to VCS (traversal)

from VCS to CUCM (neighbor zone)

Do you have any endpoint

Do you have any endpoint registered on VCS that you could test with? If you have a video endpoint, i would temporarily move it to the VCS for testing calling between VCS <>CUCM.

I used x-lite software it

I used x-lite software it registers with VCS and I make a call from VCS to CUCM and from CUCM to VCS. it should be OK. I faced some problems in this software so that I have created another discussion to see if someone can recommend another software.

Ok, what do you have for

Ok, what do you have for search rules of the VCSE? What are you dialing from the outside to get to CUCM?

Form Outside I'm dialing 1800

Form Outside I'm dialing 1800@MyRealIP_Address.

I am making the call from H.323 Endpoint. when I checked call history I found the incoming call number is 1800 only so I have created a transform to change 1800 to 1800@domain.com

 

Transform:

18(..)  Replace by 18\1@domin.com

then a search rule with (.*)@domain.com leave and forward it to traversal zone. (VCS)

 

by the way the URI directory on CUCM is 1800@doamin.com

I was thinking about your

I was thinking about your post (+5) (It looks like the neighbor zones to CUCM doesnt exist) it could be firewall issue between VCS-Express and CUCM. In the other hand if it is firewall why I can reach VCS-Express from CUCM (by making call from CUCM to VCS-Express)?

VCS Express ideally shouldnt

VCS Express ideally shouldnt integrate with CUCM, only VCS Control should. Have you created search rules/zones on VCS Express to route to CUCM?
