<DIV><FONT face="Courier New" color=#000000 size=2>Device A/7941 and Device
B/7942 share 2 common codecs: G.711 and G.729a.</FONT></DIV>
<DIV><FONT face="Courier New" color=#000000 size=2>Your region config as
described below allows iLBC as MAX codec BW (max BW per call == 24

<DIV><FONT face="Courier New" color=#000000 size=2>The transcoder does not get
invoked between 2 IP phones in the same cluster if they share a common
codec.</FONT></DIV>
<DIV><FONT face="Courier New" color=#000000 size=2>As to why iLBC shows in call
stats, I have no idea - it should not as 7941 does not support
iLBC.</FONT></DIV>

instead of iLBC</DIV>
<DIV><BR></DIV><FONT face="Times New Roman">Hi all,<BR>i really can't
understand this behavior:<BR><BR></FONT><FONT face="Times New Roman">Phone A
(7941) is in device pool A which has region A. <BR>Registered IOS Enhanced
Transcoder has device pool A and is configured for iLBC.(It is physically
located at site A)<BR><FONT color=#cc0000>There is no media resource group or
list configured in all the cluster.</FONT> So all the resources are shared
equally upon request i guess.<BR><BR>Phone B (7942) is in device pool B
which has region B. (another siteB)<BR><FONT color=#cc0000>Region A<->
Region B has iLBC configured.</FONT><BR>Hub_none location is configured in
device_pool A.<BR>Location B has 80kbps configured and is lossy
configured versus hub_none.<BR>Location B is in device pool
B<BR><BR>Phone A can talk with phone B whoever calls the other.<BR>When A
calls B or B calls A before the other answers the call, ilbc is shown in call
statistics.<BR><FONT color=#cc0000>When the call setup is finished and they
talk, the codec on both ends is g729!</FONT>!! I have nowhere configured g729
in any region!! how is this possible?<BR>Also, phone B calls through the voice
gateway in site A and through PSTN. The codec from phone B to router is
iLBC!!<BR>Also, phone B calls a trunk configured in site A and listens to
voice-mail. The call is also iLBC!<BR>Voice gateway/trunk has the same
settings as the phone A (that is: a device pool A and MRGL
none.<BR></FONT><FONT face="Times New Roman">So i guess, the transcoder is
working fine.<BR><BR>What am i missing?<BR>Why can't the two phones talk in
ilbc? 7941 can't use the transcoder which is in the same
site?<BR><BR>Thanks<BR>Anthony<BR></FONT><BR><BR>
