features of call routing will be affected:

Gatekeeper single point failure.

•

The H.323 Service will go out of service.

•

No switch transfers will succeed.

The agent reserve timer can expire before the call arrives, allowing a
different call to reach the agent that does not match the call data previously
sent to the agent by the Unified ICME software.

Outbound Alternate Endpoint functionality
not fully supported when transferring to
agents reserved by Unified ICME.

Use the router requery feature instead.

The ASR/TTS vendors currently only support g711ulaw for voice
recognition and synthesis.

G711ulaw is required codec when doing
ASR/TTS.

When an IP-originated call arrives to an IOS gateway for VoiceXML

Configuring a Gateway

From the Device Management menu, Gateway option, you can add a pre-configured IOS Gateway
to the Operations Console. Once added, you can execute a subset of IOS Gateway commands
on the Gateway from the Operations Console.

The Ingress Gateway is the point at which an incoming call enters the Unified CVP solution.
It terminates TDM phone lines on one side and implements VoIP on the other side. It also
provides for sophisticated call switching capabilities at the command of other Unified solution
components. It works with either H.323 or SIP protocols, and also supports MGCP for use with
Unified CM.
