TCL on outbound Dial Peer

[AshG]

I have simple TCL script configured on outbound dial as "service name out-bound".  However its not working.

My call fails and even the TCL script doesn't get executed. I have tried to collect TCL logs via debug but there is no logs which makes me believe that TCL script doesn't even start.

Does TCL in the outbound dial peers needs some specific starting point for it to be recognised ?

First I will check if out bound dial peer is really outbound. Remove "out-bound" keyword, remove service...etc., use anyway to verify the dial-peer is out bound.

2nd, check state machine -

set fsm(CALL_INIT,ev_handoff) " act_Setup

GETDEST"

use ev_handoff for outbound instead of ev_setup_indication.

Finally if there is anything error in script, script will be terminated before the triggered.

What debugs did you turn on ?

Hi yawchen,

Dial Peer is outbound as calls does connect if I do not apply any service to it.

However If I apply service, calls stop working.

I have following debugs enabled:

debug voip application script is ON (filter is OFF)

debug voip application tcl commands is ON (filter is OFF)

My State Machine is like this :

set StateMachine(CALLINIT,ev_handoff) "CallSetup same_state"
set StateMachine(any_state,ev_setup_done) "CallSetupDone same_state"
set StateMachine(any_state,ev_disconnected) "Disconnect same_state"

# Set initial state in FSM to CALLINIT triggered by event ev_handoff
fsm define StateMachine CALLINIT

Hi Ashish,

Please collect the logs with debugs "debug voip app" and output of "sh call app voice <app name>".

Please make sure there are no errors in your script.

Thanks,

Hi Raghavendra,

I can not see any errors in application itself as gateway loads the script successfully.

Logs attached as requested.

Thanks

Thanks for sharing logs. From the logs looks like 402 is your incoming dial-peer and 404 is out going dial peer, did you apply script under 404 dial peer ?

Thanks,

Raghavendra

Hi Raghavendra,

Yes, you are right. 402 Incoming dial peer and 404 as outbound dial peer.

Service is applied to 404 dial peer.

Its ASR 1001

[Raghavendra G V]

looks like you have enabled WSAPI, not sure if TCL IVR will work  with WSAPI .Let me check and get back to you.

Thanks,

Can you please remove the service then turn Tcl debug re-apply

application

  service servicename flash:outboundtcl.tcl

at this time monitor if there is any error

Is there a reason you use out-bound dial-peer ? The call setup you have you can do it incoming as well

Can you please show related IOS config ? dial-peers ...ect.

[Raghavendra G V]

Hi Ashish,

Can you please try to apply script under incoming dial peer and see whether script got triggered. just to confirm your using wsapi as well right.

Thanks,

Raghavendra

[AshG]

Hi Raghavendra,

Yes, if apply TCL script on inbound dial peer it does get triggered and works fine. I can confirm that we have WSAPI configured on the router.

Yawchen: There is no real purpose of this script, we are just type testing this router and created script to test TCL feature.
