Can you pastebin the configuration you are using? Also, get a console log of working and non-working calls. Use "FreeSWITCH Log" as the syntax highlight. (use pastebin.freeswitch.org) Thanks, MC On Thu, Nov 17, 2011 at 11:33 AM, Victor Chukalovskiy < victor.chukalovskiy@utoronto.ca> wrote:

Hello,

I'm looking for some help with the following: an answer confirmation + custom ringback used to work Ok when placing call out via SIP. Now, when I place a call out using analog line and mod_freetdm (dahdi mode), the calling party hears no ringback (dead air) where I expect custom ringback to be played.

My successful call scenario: incoming call is answered and custom ring-back is played all the time while call-hunt tries to find someone who picks-up the line and presses group_confirm_key. What I like is that my ring-back is played regardless of what signalling state outbound SIP calls take all the way until one of them is answered by group_confirm key.

My failed call scenario: The same, but whenever call goes out through FreeTDM ringback is no longer played as soon as FreeTDM marks channels as answered. Dead air is played instead. I'd like to send a custom ringback instead of this silence regardless of what FreeTDM thinks all the way until group_confirm key is detected. Instant ringback makes the trick, but occasionally it triggers fast busy which makes it unusable.

Thanks for looking, Victor
