Call from VCS-Express to any Endpoint

[JustForVoice_2]

Hello,

I want to configure VCS Expressway to make call to any video endpoint, I think I have to configure it to understand all endpoints addresses like:

SIP URI: abc@domain.com

H322: abc@domian.com

IP address

Could you please help me to determine all possible addresses so I can configure the required transforms and search rules.

Thanks in advance.

The VCS will understand all those address types without issues, as Cisco products use them.  With that said, it also depends on your dial plan, such as any transforms and search rules you might have in place.  Take a look at the VCS Basic Configuration for Control with Expressway Guide, as it has an overview of a suggested dial plan.  It's when you want to include 3rd-party products such as Polycom etc that make the dial plan have to be more compatible.

thank you but maybe my question is not clear

I am NOT asking about my dial plan, I want to prepare the vcs to be able to dial any endpoint in the world .

so I want to specify all possible address formats and configure the VCS to accept these formats and send the call to the right party

Note: All what I need is the perfect way to call endpoints not managed by my company, my question is how to call from my company to any other company.

You don't have to tell the VCS-E about any of the different address formats, as Patrick said, see the deployment guide, and pages 16 to 30 in particular; http://www.cisco.com/en/US/docs/telepresence/infrastructure/vcs/config_guide/X8-1/Cisco-VCS-Basic-Configuration-Control-with-Expressway-Deployment-Guide-X8-1.pdf

This will give you the ability to call other end-points using IP address, SIP URI, E.164 Alias as well as host name (requires A-record lookup and UDP turned on).

Thanks I'll check

As I said, the VCS will understand the address formats you'd like to use, but it will also depend on how your VCS dial plan is setup.  If you have a transform or search rule in your dial plan to alter the dialed address, than you could potentially not get the results you want.  You may not have been specifically asking about your dial plan, but a VCS dial plan is what makes calling other endpoints and how possible.  As I said, and Jens pointed out again, check the deployment guide, there is a recommended dial plan that will work for you and most anyone on the pages he Jens mentioned starting with page 16,

Hi,

I read this document before and I almost have configured my VCS and VCS Expressway according to it, but I asked my question because I saw this document is not enough.(as per my understanding)

 My case is:

EX90 & 60 endpoints registered with CUCM – SIP Trunk--> VCS --> VCS Express.

No endpoints will register to VCS or VCS express.

The document contains the following steps:

1. Transform to add @domain for any address does not has the domain (this is not required in my case)
2. Local zone search (this is not required in my case)
3. Traversal zone (it is a must).
4. Traversal zone search rule (it is a must).
5. DNS zone and DNS search rule (it is a must).
6. External unknown IP address routing (it is a must).

I asked my question because I think some dialing methods are not addressed in the previous configuration, like:

12345@90.90.90.90 (number followed by @ then the real IP address)

OR

90.90.90.90##1234 (Real IP address followed by ## then extension )

Please if I am wrong correct me.

Thanks in advance.

You are correct, the guide doesn't cover every scenario.

12345@90.90.90.90 (number followed by @ then the real IP address)

The VCS will automatically understand this format without any configuration on either VCS Control or Expressway.  If the IP address after the @ is your VCS IP, you could transform that to one of your SIP domains if you like or simply remove the IP portion, otherwise if it's not of your VCS IP, but an external IP for instance, nothing is needed.

90.90.90.90##1234 (Real IP address followed by ## then extension )

This is a Polycom formatted address, this coming into the VCS will be understood and the VCS will see it correctly.  However, if you expect to call this type of address from inside through the VCS, you'll need to create  a regex transform it to something the VCS will understand, such as:

pattern:  (.+)##(.+)

replace:  \2@\1

Hope this helps.

Thank you too much for your help.

The main idea from my post is to know the possible addresses that I could dial. and I have to address in my configuration.

in other words, do I have other possible addresses that I should take care about the other than:

ext@IP address

IP Address ##ext

I want to create a configuration accept any dialed format, I do want to get a call each time one of my customer wants to call new format

No problem, I'd suggest you use the Tools > Check Pattern or Locate tool to help make sure any transforms you want to setup will work the way you want, will greatly help out.

Remember to select replies as "correct answer" for those that might have the same issues or question.  Anything else, just ask, I'm sure someone might have the answer.

Just keep in mind, the VCS understands alias@IP, alias@domain, or simply IP if calling to an external system outside your network and not registered to your VCS.
