Hi,
 
Currently i'm trying to run a CVP Standalone 7.0(2) outbound_dialing_in_CVP application, but seems i have issues on the call to the cvp_dialer.tcl script, the attempts to dial the phone numbers are exausted every time i've tryied.
 
Here is a portion of my configuration:

I've noticed that on the database on every try it does to attempt to place the outbound call it returns a reason code "dialer_resp_timeout".
If you'd like, there is some logfiles attached.

Hi Paul,

Thank you for your interest, i've attached the syslog file whith the deb ccsip mess debug enabled. I think i need a review with a big cup of coffee besides.

Regards,

Hi Paul,
 
I've taked the logs you comment for a cleaner reading.

Thank you very much Paul,

For this time seems the call is not stablished at all, the phone rings form an unknown source and i can answer, but no audio is on the call and seems on VXML Server Activity logs call is getting terminated once i hang up but is not falling into the steps to write the result to the database.

So my dial peer configuration looks as follows

dial-peer voice 7788000 voip
service outbound
max-conn 10
signaling forward unconditional
incoming called-number 7788000
dtmf-relay rtp-nte
codec g711ulaw
no vad

I'm without options till now, but a ring is a step forward to keep this script running, i appreciate your help.

Regards,

If you don't use the global setting then in your particular config you'd need to have signaling forward on both your 7788000 and 7780000 dial-peers. As it is now, the SIP INFO message tunneling the request is being sent to the dialer session but the response can't get back to the CVP application with the call outcome so the script never resumes and nothing gets played. You could of course use a single combined incoming and outgoing dial-peer with both incoming called number and destination pattern configured on it.

Subsequent VoiceXML transfers should work absolutely fine; I've never
had a problem with them.

Q.  How is cvp_dialer invoked?

1. 
The custom Makecall element generates a VoiceXML document which uses an
<object> element to temporarily handoff the call leg to the TCL
script cvp_obcallreq.tcl, passing an argument string containing the
dialing parameters derived from the Makecall element settings.

2.
cvp_obcallreq.tcl sends a SIP INFO message to the cvp_outbound.tcl
session that's active at the calling end of the polling call.

3.
cvp_outbound.tcl hands-off the originating end of the polling call to a
new cvp_dialer.tcl session together with the dialing parameters.

4.
cvp_outbound.tcl immediately re-polls to initiate the next outbound
call if there is one ready to go.

5. cvp_dialer.tcl is running in
parallel and makes the outbound call and returns the call outcome back
to cvp_obcallreq.tcl via a SIP INFO message when the attempt is
established or fails due to busy, no answer, etc.

I seem to
recall there's a diagram in the config document that shows the flow.  
Also the mechanism is documented in a Networkers session slide deck
BRKUCT-3015 Advanced Tips and Tricks for Self-Service Application
Development using Cisco Unified Call Studio which seems to have become
pretty much public domain if you search for it.  Also, I've attached the
section on the outbound mechanism as the whole deck is a bit big.

Hope
that helps to explain it a bit.

Claudio,
Your network doesn't like the number you're sending so I'd start with a "deb isdn q931" trace.  Have you tried the same gateway config and POTS dial-peer to make normal outgoing calls to the PSTN from an IP phone?   If those work, then I'd certainly try comparing the ISDN debug for both of them.
