CCNA Voice Lab Manual PSTN TCL Scripts

killuah72killuah72 Posts: 60Member ■■□□□□□□□□
Has anyone successfully used the TCL scripts in this book to play the audio files when dialed?

I can call across the PSTN to the other site just fine but when I try to dial the numbers in the PSTN, the music never plays. Was pretty excited to call 911 / 9911 and hear some badass music play..

Here's the script:

PSTN_Simulator#more hq_911.tcl
proc init { } {
global param
set param(interruptPrompt) true
set param(abortKey) *
set param(terminationKey) #
}
proc act_Setup { } {
global dest
leg setupack leg_incoming
leg proceeding leg_incoming
media play leg_incoming flash:hq_911.au
fsm setstate CALLDISCONNECTED
}
proc act_Cleanup { } {
call close
}
init
set callfsm(CALL_INIT,ev_setup_indication) "act_Setup,CALLDISCONNECTED"
set callfsm(CALLDISCONECCTED,ev_disconnected) "act_Cleanup,same_state"
set callfsm(CALLDISCONNECTED,ev_disconnected) "act_Cleanup,same_state"
set callfsm(CALLDISCONNECTED,ev_media_done) "act_Cleanup,same_state"
set callfsm(CALLDISCONNECTED,ev_disconnect_done) "act_Cleanup,same_state"
set callfsm(CALLDISCONNECTED,ev_leg_timer) "act_Cleanup,same_state"
fsm define callfsm CALL_INIT



The hq_911.au file is in flash: and the music is about 1m30s long.

Here's the debug when I dial 9911:

service local flash:mrrogers.tcl
!
service us_800 flash:us_800.tcl
!
service ld flash:ld.tcl
!
service 911 flash:hq_911.tcl
!
!



Hope someone can help!

    Do you have a VOIP Dial-Peer on the PSTN router to the TCL in flash? Off the top of my head, something like this:

    dial-peer voice 911 voip
    service 911 <- TCL Script name
    destination-pattern 911
    session target ipv4:1.2.3.4 <- PSTN Router IP (itself)
    incoming called-number 911
    dtmf-relay h245-alphanumeric
    codec g711ulaw
    no vad

    This is what I configured per the book:

    R1:

    dial-peer voice 911 pots
    description Emergency Services
    destination-pattern 911
    port 0/0/0:23
    prefix 911
    dial-peer voice 9911 pots
    description Emergency Services
    destination-pattern 9911
    port 0/0/0:23
    prefix 911




    PSTN:

    dial-peer voice 911 pots
    service 911
    incoming called-number 911

    Make sure that the application is running:

    show call application sessions

    You can also try to start/stop the TCL, and manually load the prompt file:

    call application session stop id 50A0 <- obtained from the show command

    call application voice load 911

    audio-prompt load flash:hq_911.au

    That show command doesn't give me anything. Maybe that's the issue.

    I am having the same issue.

    I think I found a resolution, but I don't fully understand it (see notes), so hopefully someone else can explain some of these things?

    First, when you type the below service commands:

    application
    service ld flash:ld.tcl <--these are case sensitive. Use "dir flash:" to make sure of the name.
    service <add more> <---the writer made it seem like you need to exit each time...you don't.

    Make SURE they all say "SUCEEDED" as below. Mine were saying failed for various reasons.

    *Sep 11 20:35:30.062: //-1//HIFS:/hifs_ifs_cb: hifs ifs file read succeeded. size=770, url=flash:ld.tcl
    *Sep 11 20:35:30.062: //-1//HIFS:/hifs_free_idata: hifs_free_idata: 0x4B4335FC
    *Sep 11 20:35:30.062: //-1//HIFS:/hifs_hold_idata: hifs_hold_idata: 0x4B4335FC


    show call application sessions <---Should get nothing here still, just like after following book

    session <--This is what the book left out...enter this session command
    start <name of instance> <name of app> <---This is the command structure
    start ld ld <---This is what I used
    Started instance ld of application ld

    NOTE: Make sure each time you start one, it says "Started". Again, these can fail for various reasons. Also, not sure what "name of instance" is, so maybe someone can explain that. However, I know for sure that app has to be the same as the service name, not the .tcl name (just in case you named them differently, like 911 and hq_911.tcl. Use 911, not hq_911).

    show call application sessions
    Stopped Sessions
    Instance Name App Name State
    international international stopped
    service_codes service_codes stopped
    ld ld stopped
    911 911 stopped
    toll_free_800 toll_free_800 stopped


    Finally, we have some output here! However, I am not sure why they say "stopped", unless that is like an "idle" thing, where they move to a start/run/? state when actually in use. I haven't gotten that far due to a bad VWIC-2MFT-T1 card that wasted a good day of off and on troubleshooting my setup trying to find what blew up.
