Hi!


I'm trying to configure basic AA on IOS using Cisco's public TCL scripts. Here is my config:


application

service aa flash:/app-b-acd-aa-2.1.2.2.tcl

paramspace english index 0

param menu-timeout 1

param dial-by-extension-option 9

param handoff-string aa

paramspace english language en

param max-time-vm-retry 10

param aa-pilot 15672579882

param max-extension-length 4

paramspace english location flash:/

param second-greeting-time 30

param welcome-prompt _bacd_welcome.au

param number-of-hunt-groups 1

param call-retry-timer 10

param max-time-call-retry 10

param voice-mail 2077

param service-name call_queue

!

service queue flash:/app-b-acd-2.1.2.2.tcl

param queue-len 10

param aa-hunt1 7701

param queue-manager-debugs 0

param number-of-hunt-grps 1


dial-peer voice 1567258 voip

service aa

session protocol sipv2

incoming called-number 15672579882

dtmf-relay h245-alphanumeric

codec g711ulaw

no vad


All seems to be OK, but caller hears strange "scratch" sound instead of greeting. *.au files are OK, and playing correctly on computer.

You can check it out yourself - there is real number on dialpeer.


deb voip appl script:


*Jun 22 17:20:50.510: //4//TCL :/tcl_PutsObjCmd: TCL B-ACD: >>> B-ACD Service Running <<<

*Jun 22 17:21:04.358: //359//TCL :/tcl_PutsObjCmd:

proc init_perCallvars

*Jun 22 17:21:04.358:

*Jun 22 17:21:04.358: //359//TCL :/tcl_PutsObjCmd: TCL AA: ++ Playing Welcome Prompt and options menu ++

You cannot record .au files straight on the PC, router wants a special format not easy to prepare.


You can record them from any phone with a recorder script that I wrote:

Have you tried your recorded files before the cisco files ?

Now it works with Cisco's files, I'm played with configuration and router reloads...


The second q. is: how to get G729 encoded files? I need it in production environment instead of G711ulaw.

Googling does not gave me much interesting...

Why do you need g729 files ?

I have a g729 SIP PSTN connection and the ip-phones in few offices everywhere with g729 to avoid transconding and save bandwith.


The only place where I'm using g711 is one unity express module in central office.

You can use some software like cooledit. Note, "save as" is not enough, you must use the actual recoding function.
