Hi!
Sorry, I haven't understand your setup! Please take a look at the follwing figure. Where is the great delay? Between which messages?
UA 1 proxy UA2 | | | |1. INVITE | 2. INVITE | | --------------------> | ----------------------> | | | | | 4. 180 Ringing | 3. 180 Ringing | | <------------------- | <--------------------- | | | | | | | | 6. 200 OK | 5. 200 OK | | <-------------------- | <--------------------- | | | | | | | | 7. ACK | 8. ACK | | ------------------> | ---------------------> | | | | | | |

My setup: I use a proxy for dialing. The proxy has a static IP address. The callee can be behind a NAT or on a static IP address and the call will take a long time to connect. I have watched the traffic at the caller end and it is the same (long pause).
Any other possibilities?
Thank you for your time.

That all depends on your setup.
Do you use direct IP dialing or do you use a proxy? Where is the proxy - in your local network or somewhere in the public internet? Where is the callee located - same network or somewhere else? It might be also useful to watch the network traffic at the callees site and at the ser proxy.

I ran ngrep -d eth0 X.X.X.X (Where X.X.X.X is my
IP
address) and I didn't get a lot of DNS queries. I couldn't see any activity on my IP address until I heard a ring (after about 15-20 seconds).
What would be some other causes for this problem?
Thank you for your time.

There can be a lot of issues, e.g. I often find
long
call setup delays caused by several DNS lookups (either by the
client
or the proxy) which may take some time if the DNS server is slow.
You would have to use ethereal (or other packets sniffer) and watch all traffic related to your call to resolve this
issue.

I have noticed that when I attempt to call
another
user it takes a long time to make the
connection.
I'm guessing this is a configuration issue
since I
have an ADSL connection. Does anybody know
how I
can
solve this problem?
Thank you for your time.
