New subject: [Serusers] Call connections take too long

22 Dec 2003

If the problem is between dialing and message 1, than this has nothing
to do with ser, because ser is between message 1 & 2.

Which user agent do you use?

What is "long pause"? 0.5 seconds, 5 seconds, 50 secondes?

Have you watched if there is some other traffic caused by your user
agent (capture the network traffic directly at UA1, not at the proxy)?
e.g. DNS lookups, NTP requests, ...

regards,
Klaus

 My delay is from the time that I dial the number to
 the time that "1. INVITE" happens.

 In ser.cfg I have the following in route()
 if (uri=~"sip:1[0-9][0-9]+@.*") {
                 rewritehostport("X.X.X.X:5060");
                 #forward the request now
                 if (!t_relay()) {
                         sl_reply_error();
                 };
                 break;
         };

 I found that in the documentation for SER but I don't
 really understand what it means.
 I am used to the Asterisk syntax for phone numbers so
 I'm confused when I see "1[0-9][0-9]+@.*"

 So anything that starts with 1 is sent to my gateway. 
 But I don't understand "[0-9][0-9]".  How many digits
 does this include?
 I'm only calling in North America, so I need 10 digits
 after the initial 1.
 Is it possible that I have it configured to look for
 more than 10 digits, so it waits until it times out
 and then sends the digits it has received?

 If that is the problem, how do I fix it?

  Hi!

 Sorry, I haven't understand your setup! Please take
 a look at the
 follwing figure. Where is the great delay? Between
 which messages?

 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.
