CVP 4.X/ICM - Distributed Gateways - Routing methods

we have a mixed environment of combo IOS ingress/vxml GWs and some that are separated. It is a smaller deployment. Wanting a standard routing mechanism, what is the best way to route with CVP/ICM comprehensive model in an H.323 environment


- by customer (associating lables to customers)


- by using sigdigits/settransferlabel (routing with tech prefix in the GK)



we have not been successful using muliple customers under the customer instance. Just won't throw back the right label.


Using the sigdigits method, we have issues trying to use redundant VXML GWs (primary and secondary). We can get the label back to the GK and route to the primary VXML GW, but if that primary VXML GW is down, how do you get the call to the secondary VXML GW? We dont want to load balance the VXML GWs, b/c they are spearated between two data centers with a high speed pipe between them....so they are registered with different tech prefixes..

Hi,

The best practices and explainations for this process is in the CVP 4.0 Configuration and Admnistration Guide that you can find here: http://www.cisco.com/univercd/cc/td/doc/product/icm/isn/cvp40/.


The Chapter is called Configuring the H323 Devices and VoIP.


If you have any specific questions about that chapter, I can answer them for you.

You want to share ICM/CVP with multiple customers? The standard way is NAM with multiple CICM's and CVP is on NAM, each customer has own DN's and scripts, the queue label can be the same, when ICM script triggers this label, CVP sends calls to VXML gateway by this label together with external script name and media file names, so VXML gateway can still play different prompts upon script's instruction.


For the question on how GK sends to secondary VXML, zone prefix with priority.


Hope this help.
