Cisco CVP Standalone Outbound

Muhammed Ashiq · ‎05-12-2020

Dears,

We are trying to implement Cisco CVP Standalone Outbound as described by Engineer Mr.Paul Tindal.

https://twitter.com/tindallpaul/status/919638559702822912

Below are the setup we are using,

Cisco PCCE 12.0

Cisco CVP 12.0

Cisco VVB 12.0

Voice Gateway 29XX

Did anyone implemented this setup.Need help in VVB Configuartion.

ptindall · ‎05-13-2020

There's not really much to do differently on the VVB.

Start with the original non-VVB materials on Devnet CVP samples to understand how it works and for a quick-start outbound DB based dialing list if you need it.
Then read and follow the specific notes at https://app.box.com/s/qp9sbeh0zcf7z3bp2xb2jop6fprox9ma for using the VVB edition.
Add the VVB compatible version of the MakeCall custom element to CVP Studio and run-time.
Build and deploy your outbound test Studio app that uses the MakeCall element.
Configure the inbound trigger DN on VVB admin to map to the CVP Standalone application you just deployed.
Start the outbound app on the gateway/CUBE as normal.
Use "deb voip appl script" for diagnostics.

Dear Paul,

thanks for the response,we have followed the steps .Unable to start Outbound dialing.

We are getting following from the Voice gateway,

May 13 09:55:09.869: //-1//TCL :EE3F4BC6B0000:/tcl_PutsObjCmd: ******* CVP_OUTBOUND: started poll timer

From the VXML application activity logs,

Makecall_01,element,error,error.unsupported.objectname: classid=com.cisco.callhandoff service=cvp_obcallreq.

Thanks.

ptindall · ‎05-13-2020

That is either the non-VVB MakeCall element you're using or the correct VVB compatible one that hasn't identified the browser type. Post the activity log up to and including the MakeCall.

Muhammed Ashiq · ‎05-14-2020

We are going with the old Setup now ie,VXML gateway mode. where will be the configuration is missed.

ptindall · ‎05-14-2020

The warnings you highlighted can be ignored. These are local params that haven't been assigned to a namespace.

Muhammed Ashiq · ‎05-14-2020

Below are the logs we are getting.

We are having both VXML GW and Voice GW in one.

CVP Standalone

DNIS=2001

Clid=2255

No dialing happening.

A SIP INFO message should be sent between CVP_OBCALLREQ and CVP_OUTBOUND. As the trace shows one never arrives, check you have "signalling forward unconditional" enabled globally under voice service voip or at dial-peer level for the polling call. Turn on "deb ccsip mess" to check the SIP INFO is sent.

Paul

Muhammed Ashiq · ‎05-15-2020

Unconditional forwarding is enabled in globally already.

Please find the below debug sip info.Thanks.

Not much information as it stands as it doesn't even have the original SIP INVITE and there's no SIP INFO. Send me a full trace with "deb voip app script", "deb voip app tcl" and "deb ccsip mess" covering the full call scenario.

Muhammed Ashiq · ‎05-15-2020

Attaching file with debug enabled.

ptindall · ‎05-15-2020

The polling leg is receiving the SIP INFO containing the dialing record but the cvp_outbound TCL application isn't seeing it. Check your gateway SIP config to make sure there's nothing blocking signalling.

Muhammed Ashiq · ‎11-24-2020

Hi Mr.Paul,

Can we use the same TCL script for invoking multiple applications ?

Let's say we have two VXML applications to be run on this setup.

ptindall · ‎11-24-2020

Using it as published, without any modifications, it's built to make calls to a single number which in turn maps to a single Studio app. To trigger an additional Studio app in parallel, you would have to run another instance of the outbound TCL that uses a different polling number. The Studio app that actually does the call handling once the customer answers can be changed at the app level by passing control to another app via subdialog or app transfer elements. In that case you'd only need to use a single TCL instance.

So, it really depends on the precise use case. If the requirement is to use different scripts containing the MakeCall element in parallel then multiple TCL instances would be needed. If the multiple handling cases can be worked into a single Studio app then only a single TCL instance would be required.

Other possible approaches would be to modify the TCL to cycle through a list of polling numbers, or use a weighted list etc. I'm not entirely convinced it's worth the additional complexity when you can always just run multiple instances to achieve the same thing.

Muhammed Ashiq · ‎12-20-2021

Hi Mr.Paul,

If we want to use multiple instance of what are the parameters to be changed ?

ex:-

!

application

service cvp_outbound_1 flash:cvp_outbound.tcl

.............

!

application

service cvp_outbound_2 flash:cvp_outbound.tcl

.............

!

session

start ob cvp_outbound_1

!

session

start ob cvp_outbound_2

!

Is this would be enough ?
