Make sure that all of your SIP clients are set to "canreinvite=no" in<br>
"sip.conf". The default is "canreinvite=yes", which allows RTP to<br>
bypass Asterisk. Certain things (codec translation, playback of audio<br>
files, etc.) require Asterisk to be in the RTP path, which may explain<br>
why you're recording some of the calls.<br>
<br>
If you're still missing calls, make sure Oreka is configured properly in<br>
"config.xml". In particular, the "AllowedIpRanges" and<br>
"BlockedIpRanges" settings provide IP address filtering at the Oreka<br>
level. In general, I've had to configure these to prevent getting two<br>
recordings of each call (since Asterisk acts as a B2BUA) but your<br>
configuration may be too strict.<br>
<br>
Running tcpdump/Wireshark on the Oreka server will let you see exactly<br>
what's being mirrored. There is even a setting in Oreka named<br>
"PcapFile" that will let you playback the packet capture file over and<br>
over until you're satisfied with your configuration.<br>
