asterisk users - Nov 2003 - Echo and Call Setup suggestions

Hello,

I'm running a bone stock * box that only has SIP clients and about a dozen
cisco T1 gateways.  Some of the higher delay users complain that they
occasionally hear echo on local and long distance calls, which eliminate the
gateways as the source of the problem.  

Problem #2 is that it takes a long time for the call setup to happen, on the
order of about 8 seconds.  

I'm looking for suggestions on where to look for problems.  Thank you very
much for your advice.

Chris
