Long join times in conference bridge


#1

Using the following:

I have 9 extensions that auto answered when called. I want to get them into a conference. After 101 joins, the rest take a long time. Can you point me to how to fix this.

exten => 8800,n(next),Originate(sip/101,exten,conference,8601,1)
exten => 8800,n,Originate(sip/100,exten,conference,8601,1)
exten => 8800,n,Originate(sip/102,exten,conference,8601,1)
exten => 8800,n,Originate(sip/103,exten,conference,8601,1)
exten => 8800,n,Originate(sip/104,exten,conference,8601,1)
exten => 8800,n,Originate(sip/105,exten,conference,8601,1)
exten => 8800,n,Originate(sip/106,exten,conference,8601,1)
exten => 8800,n,Originate(sip/107,exten,conference,8601,1)
exten => 8800,n,Originate(sip/108,exten,conference,8601,1)
exten => 8800,n,Originate(sip/109,exten,conference,8601,1)

after a very long time they all eventually join but I would like it to be faster like 100 and 101

Doesn’t anyone have a suggestions. If I just ask 100 and 101 the conference works almost immediately. If I add just 102 then the conference take about 30-40 seconds to start. There has to be a reason that its delayed.

Not really, but here have a reply to not feel alone :yum:

Show us the cli output or better the full log with time stamps when this happens.

Here is the full log file when the problem occurs. As you can see after dial.c is executed, it takes 20 seconds to ring. I hope this output is helpful. Thanks.

My guess would be a DNS issue, unrelated to the conference.
