<DIV><FONT face=Arial size=2>Hi All,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>We met some problems using oh323 faststart
with cisco gateways.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Test bed:</FONT></DIV>
<DIV><FONT face=Arial size=2>source cisco 3620 -> asterisk oh323 ->
destination cisco 2600. </FONT></DIV>
<DIV><FONT face=Arial size=2>Both cisco gateways use IOS 12.3.
</FONT></DIV>
<DIV><FONT face=Arial size=2>Only g711ulaw allowed.</FONT></DIV>
<DIV><FONT face=Arial size=2>asterisk configration is very simple.
extensions.conf redirects all calls to the destination. default h323.conf is
used.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Test steps and results:</FONT></DIV>
<DIV><FONT face=Arial size=2>1. The source directly pointed to the destination
with faststart working fine. What means both cisco gateways support faststart
and the configuration is correct.</FONT></DIV>
<DIV><FONT face=Arial size=2>2. The calls had long setup delay, some
failed. </FONT></DIV>
<DIV><FONT face=Arial size=2> From the traffic log, the
destination sent fastcnnectrefused after it received the call setup message
from asterisk. The setup message had faststart field.</FONT></DIV>
<DIV><FONT face=Arial size=2> We found that oh323 set ulaw
capability to max_ms, 150. The destination local ulaw capability is 20.
After we changed oh323 to set ulaw capability to def_ms, 20, the destination
gateway no longer sent fastcnnectrefused.</FONT></DIV>
<DIV><FONT face=Arial size=2>3. All calls completed. But faststart did not been
used.</FONT></DIV>
<DIV><FONT face=Arial size=2> For unknown reason, asterisk
sent fastcnnectrefused to the source.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>We believe faststart is important for the business.
Does anybody have any experience for this problem? Maybe it is just a
configuration issue. We know OpenH323 supports faststart.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks,</FONT></DIV>
