[Freeswitch-users] delay before ringback at 183 to 180 transition

[Jeff Pyle]

Hello,

FreeSWITCH Version 1.5.15b+git~20150313T215013Z~9872c52c57~64bit (git
9872c52 2015-03-13 21:50:13Z 64bit)

I have a situation where a gateway sends a 183 with media, then a 180.
Following Anthony's advice from FS-3859 I have the following:

  <extension name="sendit">
    <condition field="destination_number" expression="(.*)">
      <action application="set"
data="ringback=/usr/local/freeswitch/sounds/ringtester.wav"/>
      <action application="bridge"
data="{bridge_early_media=true}sofia/public/$1@${host2}"/>
    </condition>
  </extension>

On the a-leg I hear media from the 183 until host2 stops it and sends the
180.  Then there's a 4.8 second delay of no RTP from FS before I hear my
ringtester.wav file.  This occurs with a tone stream as well.

The last event on the console is "Callstate Change EARLY -> RINGING" when
the 180 comes in, then "nua.c:366 nua_handle_magic() nua: nua_handle_magic:
entering" when the 180 arrives.  Then 4.8s of nothing.  Then FS resumes the
RTP with the ringback file.  There is nothing new displayed when the RTP
resumes with the ringback file.

Is this a bug, or a misconfiguration?
