Transfer audio
Answer
9/29/09 6:46 PM
Hi,
 
I have to play music while call transfer. I have configured a vxml file:
 
<transfer name="mycall" destexpr="tel:+...." transferaudio="welcome.au" bridge="true">
 
and on the cube :
 
dial-peer voice 1 voip
incoming called-number 300
service test
 
Now my problem:
 
this is a ipip gateway. I become the call from the ccm via dial-peer and have to route to the ccm via dial-peer. The call routing is OK but the application does not play the call music.
 
Have you a idea ?
 
thx a lot

I think most likely the audio file is in G.711 format.
Maybe you like to check your codec setting in dial peer
 
Thanks !

Hi,
 
I think the codec can not be the problem, because I hear the ringing tone. But I want to hear the audio.
I think the problem can be the routing situation.
 
SIP Gateway -> ASR -> CUCM7.x -> CUBS -> CUCM7.x -> DN
 
I think the callmanager accepts the call but then I can not stream the audio file back.
 
thx

Hi Patrick,
 
I would like you to check the following 3 steps.
 
1.Check on the URI,specified on transferaudio,whether the URI is fetchable.Because If the resource cannot be fetched, the error is ignored and the transfer continues;
2.Try with .wav file instead of .au file format,to confirm its a codec issue or not.
3.As you said it's IPIPGW,please check is it configured with media flow-around or flow-through cli.
 
I have suggested these steps in oreder to isolate the issue.
 
Thanks
Vijay

Hi Vija,
 
Thank you for your help.
1. ) the URI should be OK - the wav file is on the flash
2.) now I tested it with a wav file - now i have the problem, i do not hear any ringback and no audio
3.) I have configured media flow-around
 
I do not know, why the audio file is not streaming. I tested it in a lab scenario with one router and 2 sip phones and my
vxml script was ok - the audio plays.
But with my Gateway Scenario ( SIP Gateway -> ASR -> CUCM -> CUBS -> CUCM -> GW -> IP Phone ) I have the problems...
 
How can I debug the transferaudio promt ?
 
thanks a lot
Patrick

dialpeer default is G.729
 
Why don't you just keey your old config and add one more line to give it a try.

Hi Patrick,
 
Can you try to configure your IPIPGW with media flow-through CLI and try your script once again,
 
Thanks
