Inbound Call Routing GK_1 Configuration
zone local gk_1 cisco.com 10.10.10.00
*\ Must include GK IP address \*
gw-type-prefix 1#* default-technology
*\ Default for calls rec’d with no tech-prefix\*
zone prefix gk_1 8005550010 gw-pri 10 cvp_1vb1@cisco.com cvp_1vb2@cisco.com
endpoint alt-ep h323id cvp_1vb1 10.10.10.12
endpoint alt-ep h323id cvp_1vb1 10.10.10.13
endpoint alt-ep h323id cvp_1vb2 10.10.10.11
endpoint alt-ep h323id cvp_1vb2 10.10.10.13
endpoint alt-ep h323id cvp_1vb1 10.10.10.12
endpoint alt-ep h323id cvp_1vb1 10.10.10.13
endpoint alt-ep h323id cvp_1vb2 10.10.10.11
endpoint alt-ep h323id cvp_1vb2 10.10.10.13
The two Voice Browsers in the zone prefix command have equal priorities (pri 10), so under normal
circumstances the GK will route all calls randomly between vb1 and vb2. For the purpose of our
example, however, GK_1 knows that vb1 (at CVP_1) is completely Out-of-Service.
circumstances the GK will route all calls randomly between vb1 and vb2. For the purpose of our
example, however, GK_1 knows that vb1 (at CVP_1) is completely Out-of-Service.
Each of the Gateways queries its own Gatekeeper for Inbound calls, so if Gateway Huey receives a call
for 800-555-0010, it will query GK_1 for routing information, using the number 2#8005550010. Since
vb1 is Out-of-Service, GK_1 will return the IP Address of vb2 to Huey, as the target endpoint. In the
same response message (an H.323 ACF message) GK_1 will also pass the IP Addresses of vb2's
Alternate Endpoints (which in this example are vb1 and vb3 at CVP_1). Huey will first attempt to route
the call to vb2. If for some reason vb2 fails to respond to the call setup, Huey will try the alternate
endpoints in turn, until it receives a response. Huey will pass the number 2#8005550010 to the Voice
Browsers during call setup, which will in turn strip off the tech prefix 2#.

Caution
When defining a zone prefix, it strongly suggested that you use the “*” wildcard, rather than the “...”
wildcard pattern to avoid zone prefix conflicts within the Gatekeeper.

CVP Voice Browser Configuration
The Gatekeeper processes Voice Browser registration as follows:
•
RRQ registration. CVP Voice Browsers register with the CVP Zone Gatekeeper through the H.323
Registration Request (RRQ) message. As part of RRQ registration, each Voice Browser sends its
name (for example, “cvp_1vb1@cisco.com”) and IP address.

name (for example, “cvp_1vb1@cisco.com”) and IP address.
•
IP Addresses for Alternate Endpoints. The Gatekeeper allows each registering endpoint to send a
list of IP Addresses for its alternate endpoints. This registration list is merged with any alternate
endpoint information statically configured on the Gatekeeper.
list of IP Addresses for its alternate endpoints. This registration list is merged with any alternate
endpoint information statically configured on the Gatekeeper.
Note
This feature is not supported by CVP Version 3.0.
•
Supported Numbers. The Gatekeeper allows each endpoint to register with a list of E.164 numbers
it supports, but it is recommended that the Voice Browsers don't do this. The reason for this is that
multiple Voice Browsers can support the dialed numbers, but the Gatekeeper does not permit
multiple endpoints to register with the same number.

•
Technology Prefix. Each CVP Voice Browser is automatically registered with its Gatekeeper with
the Tech Prefix 2#. The Voice Browser’s software is shipped with the tech-prefix 2# pre configured.
If necessary, this number may be changed using the VB Admin’s SetTechPrefix command.
