GVP Infront of the Switch Deployment

[RDB]

Hi,

Has anyone either implemented or come across the
[b]GVP Infront of the switch[/b] deployment or architecture.
Need to implement this for the lab setup but could not find
exact details and info.

Would appreciate any inputs or document references.

Thanks.

Sure. What sort of information are you looking for? SIP, TDM???

I forgot to mention the GVP version which is 8.x
I am looking for some leads on the Infront of the switch configuration for GVP 8.x
for both TDM and IP type of architecture.

Thanks.

Hi RDB,

GVP 8 is used with SIP in most deployments, so let's focus on this scenario. In an in-front mode, GVP is configured as a trunk on SIP server. The Media Gateway sends calls to this SIP Server trunk and SIP Server forwards them directly to GVP's Resource Manager/MCP. The GVP receives the SIP INVITE and triggers an application based on the DID and the IVR Profile it is assigned to. Please note - the DID and the trunk number need to be the same. When the voice application wants to send the call back to routing, it can transfer the call to a routing point with a VXML transfer tag. The URS can then route the call to an agent - that's a classic scenario. Otherwise the IVR can simply disconnect the call in the voice application.

The behind-mode is slightly different. In that case the call is sent from the Media Gateway to a SIP Server routing point. The routing strategy can then use the Play Application block to start a GVP treatment. The URS knows where to send this treatment, because the Resource Manager is configured on the SIP Server as a Voice-over-IP service. GVP has no control over the call. After the voice application exits with a VoiceXML EXIT tag or block, URS automatically takes control of the call. URS can then decide to route the call, play a treatment or disconnect it.

Thanks Syxtus, that explanation was quite helpful.
