asterisk users - May 2004 - Long delays when talking betwwen SIP phones

I am experiencing some long delays when talking SIP to SIP (I will talk,
it it takes about 2 seconds for that conversation to reach the other SIP
phone, and when they talk back, same thing) on our local LAN. Traffic is
relatively light on our LAN. But talking SIP to PSTN works fine, no
delays. If anyone has experienced similar delays, what have you done to
correct it?
 
I have tried different codecs (GSM to GSM, ulaw to ulaw) and still the
same result.
 
I truly think this that the problem lies within the LAN, but wanted to
make sure that others have not had the same problem and it turned out to
be a config issue.
 
Any assistance is greatly appreciated.
 
Thanks in advance.............>>Greg

I would suggest you plug your * server directly into a non-managable switch as
well as the two phones and test.  That would either eliminate or prove that the
LAN is the issue.  Only reason I say a non-managable switch is that you would
know that its not something in the switch config.
