We have consistant problems with SIP calls on our server. We sit on a OC3 so bandwidth souldn't be it. Ping times to our sip server is 50ms consistantly. We are using WinXP Pro, should I switch to Windows 2000 for its bigger IP stack buffer? The odd thing is we do not have trouble with our other SIP serivces, only dialdictate. Are there any other users using SIP and having great performance? What is your secret. Thanks, Derek
