when using sip, i get alot of dropped calls

[ckwall]

When using a T1 I never had any dropped calls in my vdad report. I am doing adapt hard limit of 1 so that only one number is dialed per avaialble agent. It worked perfectly with a t1. well, i recently switched so that the dialer goes over sip to another server connected to a t1. Now I get about a 7% drop rate. When looking at it, these calls are all dispositon failed with a dialstatus of congestion. they are not actually dialing out and dropping like the definition would imply. I could use some advice on this issue. No output posted. Not sure what to share yet.

thanks

What kind of data connection is between you and your SIP carrier?

Does your SIP carrier have a limit to the number of trunks they will allow you to dial out on?

[ckwall]

the vicidial server is on an internal network connected to another asterisk server which has tdm (PRI) circuits plugged into it. I do not beleive i am limitting any calls.

on an interesting note... I set the campaign to dial with one agent always idle... i still get the dropped calls on the vdad report.

[mflorell]

Have you tried IAX trunks?

for the dialing, have you tried RATIO dialing with available-only set to Y?

[ckwall]

no and no... let me try ratio

sadly this did not make a difference.

I dont know if this has anyting to do with it, but I am getting alot of records in my cdr database that look like this:

I haven't seen this problem before when using another Asterisk server as a gateway, is the other machine using FreePBX or Trixbox by chance?

If it is getting a CONGESTION then it is most likely the gateway machine that is sending it. Can you post the dialplan path or Asterisk CLI output of one of these calls on the gateway?

[ckwall]

I am glad you replied... I needed to come back and post my findings. I took all of the dropped calls and manually dialed them. They are error messages from places like cell providers and phone companies that are answering and saying something, then hanging up. So it acts like a dropped call. Seem like the data is accurate and my research was not.
