Call Transfers and Outbound Routing
Note
In outpulse transfer mode, the CVP will send whatever digits are in the label to the Gateway for
outpulsing. It is the customer’s responsibility to confirm interoperability with the target switch.

Codec Support
There is a codec used for IVR prompting in CVP and a codec used for transfers (actually it is possible,
though not likely, that a different codec could be used by each transfer during the life of a call). As
depicted in the examples above, the ingress gateway dial-peer was configured for all possible codecs that
may be used in the life of the call (in this case we limited it to g711alaw, g711ulaw and g729r8).

Codec Support differs somewhat between CVP Queue and Transfer mode and CVP Comprehensive
mode.
mode.
Queue and Transfer: All prompts are played by the CVP Voice Browser. Therefore, it is the CVP Voice
Browser itself which defines the IVR codec through the SetCodec CLI command. It is the egress gateway
dial-peer that defines the codec that will be used during the transfer. In our example above, we chose
g729r8.

g729r8.
Comprehensive: In this mode, no prompts are played by the Voice Browser. Instead, the Voice Browser
transfers the call to a VXML-enabled voice gateway which provides IVR treatment which may in the
form of prerecorded prompts or ASR/TTS. In this case it is always the egress dial-peer that determines
both prompt codec and transfer codec. If using ASR/TTS, the codec must be g711ulaw for IVR
treatment. The transfer codec may be anything.

Miscellaneous Gateway Configuration Tasks
Determine if the Gateway is Correctly Configured for CVP?
To determine if the Gateway is configure properly, use the ‘show run’ command to a view a gateway
configuration. Use ‘copy run start’ to make changes permanent.
