[Freeswitch-users] CISCO 2811 Freeswitch IVR

Because I'm using an FXO card with voice, I added something to my
CISCO conf. Many others had the same thing:


voice-port 0/3/0
   ...
   supervisory disconnect dualtone mid-call
   supervisory answer dualtone    <---- ADDED THIS ONE
   ...



Once I added this, the FS output now just showed the following while
the phone was ringing:

2012-01-05 16:19:31.644440 [NOTICE] switch_channel.c:816 New Channel
sofia/internal/109212xxxx at 192.168.x.x

sofia/internal/109212xxxx at 192.168.x.x!


Where as previous it would show the above and also show the following:

2012-01-05 16:19:35.127883 [INFO] switch_channel.c:2456
sofia/internal/109212xxxx at 192.168.x.x Flipping CID from ""

2012-01-05 16:19:35.138384 [NOTICE] sofia.c:5296 Channel
[sofia/internal/109212xxxx at 192.168.x.x] has been answered



BUT, the IVR still started playing even before I pick up the phone.
Hmmmm.....so why is FS still starting the managed application when the
call has not been answered yet. Are we all sure that the managed
application should not be executed until the call "has been answered"
shows up in the log file?


Will have to keep testing on monday as I don't have access to the
CISCO from where i am now. I'll have to see whether the CISCO changes
had any impact on the times at which the SIP messages are sent back
and forth. Especially the 200 OK message.


Thanks again for help, maybe getting somewhere now......
