[cisco-voip] Qs: G/K Technology Prefix

[Avner Izhar]

Hi,

Tech prefix's are more targeted toward selecting the correct technical resource for the type of call.

So that you assign 2# for voice calls, 3# for video calls and 4# for h.320 video over isdn calls.

If you have different sites, I'd use a zone prefix since it also allows to use the gatekeeper for CAC between them.

HTH,

Thanks for the reply 

I am confused regarding tech-prefix functionality. For example if  we have different sites in different cities. We can group gateways in site-1 with (say) tech-prefix 1# and tech-prefix 2# in site-2. 

Is this the right concept for Technology Prefixes?

For local call the gateway will be able to handle calls locally since the dial-peer will be there. But for call that are not local how do we need to define dial-peers as well?

Regards,

Khalid

Hi,
 
You can do both, but not at the same time.
 
Normally you would want your gateway to register his tech-prefix, but some gateways will not support it and then you will need to set it up manually.

Syed - When you configure the technology prefix, they must agree and be configured on both the gateway and the gatekeep.

In cisco press ebook Cisco Voice G/W and G/K, the author says: {section: E.164 Number Resolution}

1- The Tech Prefix is optional feature.
2- To use technology prefixes:
Assign the gateway a technology
prefix You can do this on the gateway so that the prefix is registered with the gatekeeper as part of the RRQ. 

You can also configure it statically on the gatekeeper so that the technology prefix is associated with the gateway IP address.


This identifies the technology (type, class, or pool) that the gatekeeper associates with this particular gateway when performing call routing.

This means that I can assign the Tech Prefix either on G/W or the GK?

But in the next chapter (17) section: configuring basic g/k functionality, it include the Tech Prefix both on G/K and G/W. 

Is it mandatory for configure tech prefix on both g/w and g/k?

Can any one explain?

Regards,
Khalid
