I am using SER for VOIP and experiencing issues with call setup when
making VOIP to VOIP calls. With 2 end units connected to the same
server, there is a 5-7 second delay in the RTP stream when I place a
call from one IP phone to another. I also experience a delay in ring
back when calling inbound to an IP phone from a standard PSTN line. I
am new to configuring SER. I can provide more info if needed. Thanks.

James,
That is definitely not normal. I suggest the following:
- Make sure that you're signalling is ok (if you're not sure, post the ngrep
output of a call setup). Do you use auth in ser? RADIUS? exec_dset? Make sure that the
answer times are ok.
- Use ethereal or some other listener at one of the client ends to see what's going
on
g-)
