[Freeswitch-users] "VETO state change from RING to UP" - Why?

[Andrea Coslovich]

Hello everybody!

I posted this message a couple of days ago but I forgot to put a subject and, probably due to this reason, it wasn't noticed and replyed. So now I try again, hoping this doesn't annoy you too much. I'm really sorry for the inconvenience and I apologize with all the list subscribers.


I have an A104 Sangoma board and I'm developing an application based on FreeTDM library.

In my application I need to answer to incoming calls as soon as possible, so I've tried to call "ftdm_channel_call_answer(channel)" immediatly after the receiving of the "START event" and I was really displeased when my call didn't rise and I saw a "VETO state change from RING to UP" message in my log. As far as I know the ISDN protocol allows to send a CONNECT message immediatly after receiving a SETUP, so I'm wondering why I cannot call the "ftdm_channel_call_answer(channel)" in a "RING" state. Is this a problem of my software or the normal behaviour of the FreeTDM library? 

Thanks a lot for any feedback!

Kind regards,
Andrea Coslovich
