thanks everyone.

Sheeraz that's a sample studio app provided by Cisco Developer Network team.

I have attached sample application and document.

Thanks for reply Amir, my concern is which party is working as a dialer. Either TCL script runnong on VXML VG will dial or is there any option in VXML Studio containing "make call" or "dial" element which will forward the request to VXML VG.

Waiting for your reply thanks

here is your answer,

  1. A tcl      script runs on the egress gateway and periodically polls the VXML gateway      to see if there is an outbound call to make.  It does this by making a SIP call to a      service running on the VXML gateway.

  1. The      VXML gateway service makes an HTTP request to VXML server requesting it to      run the outbound application.

  1. The outbound application sends a SQL      request to the database which runs a query looking for rows with a status      of OUTDIAL_PENDING.

  1. Database      returns a single row indicating either a valid DNIS to call or ‘xxxx’      indicating that it has no outdials to make at the moment.

  1. If      there are no outdials to be made:

  • the appropriate status will be sent back to the VXML gateway which will simply disconnect the polling SIP leg that originated from the egress gateway.  The tcl script on the egress gateway will sleep for X seconds (configurable) before beginning a new polling cycle.

If there is an outdial to be made:

  • the DNIS to call, the CLI to use for the outdial, and optionally the ring-no-answer timeout (rna) and user-to-user info (uui) will be sent back to the VXML gateway.

We had tried solution shared by Cisco experts for CVP VXML standalone outbound dialing but ended up with a problem. In our case call initiated by dialer and it starts ringing on our mobile phone but then automatically disconnected after some time (around three seconds). In VXML logs it has been observed that every call is being disconnected after 15 seconds. Here are the details of our platform where we are testing this solution. 

Here is the detailed description of our case. Please help us to troubleshoot issue.
