Leg States

Lisandro Quinteros — Thu, 09 Oct 2014 20:17:17 GMT

Hi everyone , I am working with a CVP implementation.. which has a survivability tcl script so when CPV is unreachable (ex branch is on SRST) .. I could execute a custom TCL script...

I have made a basic tcl that plays greating message .. check out of hours.. etc....

I developed the tcl just triggering him from a pots dial-peer (but not using cvp) and works great....

When I configure the real scenario with cvp and branch office on srst.... I could see the survivability.tcl from cvp does a handoff to the application that I could define using a param..

So in my TCL I added

set fsm(CALL_INIT,ev_handoff) "act_Setup GETDEST"

The problem is when in act_Setup when I tried to:

leg setupack leg_incoming

leg proceeding leg_incoming

leg connect leg_incoming

It says...

Illegal Operation: Leg not incoming or in wrong state

*Oct 9 20:01:01.409: TCL script failure errorInfo:

Illegal Operation: Leg not incoming or in wrong state

So the first thing I did was... try to do a

connection destroy con_all

Illegal Info Tag: Should map to atleast one Connection

*Oct 9 19:36:02.353: TCL script failure errorInfo:

Illegal Info Tag: Should map to atleast one Connection

Then I did...

[infotag get evt_connections]

No connection is display ...

[infotag get evt_legs] and [infotag get evt_legs]

Both shows only one leg EX 352

So for what I can see the leg incomming is there but "in wrong state".. What could I do ?

Regars..

Hi Lisandro,

You need to check the leg state before issuing these commands as below.

set legState [infotag get leg_state leg_incoming]

if {$legState != "lg_005" && $legState != "lg_008"} {

if {$legState == "lg_001"} {

leg setupack leg_incoming

leg proceeding leg_incoming

leg connect leg_incoming

} elseif {$legState == "lg_002"} {

leg proceeding leg_incoming

leg connect leg_incoming

} else {

leg connect leg_incoming

}

# lg_001 --> LEG_INCOMING_FIRST

# lg_002 --> LEG_INCACKED

# lg_003 --> LEG_INCPROCEED

# lg_005 --> LEG_INCCONNECTED

# lg_008 --> LEG_OUTPROCEED

Thanks,

Raghavendra

Hi Raghavendra I have already seen that infotag on other Cisco tcl but I today I was looking for it on tcl Ivr programming guide 2.0 and cound't find it neither the lg_xxx maybe I didn't see it..

That would save my problem..

Thanks for your help

yes you can find the command in below link, not sure why it is not added in downloaded pdf.
