Can you pastebin the configuration you are using? Also, get a console log of working and non-working calls. Use &quot;FreeSWITCH Log&quot; as the syntax highlight. (use <a href="http://pastebin.freeswitch.org">pastebin.freeswitch.org</a>)<div>

          I&#39;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.<br>
          <br>
          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.<br>
          <br>
          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&#39;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.<br>
          <br>
          Thanks for looking,<br>
          Victor<br>
