Hi, I am attempting to make about ten calls simultaneously and intermittently get 'SIP/voipprovider is circuit-busy' followed by 'everyone is busy/congested at this time" I am not sure if this is related to my bandwidth to my voip provider, a configuration issue or something else. Has anyone seen this before and have any suggestions. Thanks in advance. -------------- next part -------------- An HTML attachment was scrubbed...

It might be related to bandwidth since each call takes 30-60kb depending on codec. You could try putting a "w" in front of the number to make Dial wait .5 seconds before starting. _____ From: asterisk-users-bounces at lists.digium.com [mailto:asterisk-users-bounces at lists.digium.com] On Behalf Of John Regal Sent: Wednesday, May 20, 2009 3:31 PM To: 'Asterisk Users Mailing List - Non-Commercial Discussion' Subject: [asterisk-users] ...is circuit busy message Hi, I am attempting to make about ten calls simultaneously and intermittently get 'SIP/voipprovider is circuit-busy' followed by 'everyone is busy/congested at this time" I am not sure if this is related to my bandwidth to my voip provider, a configuration issue or something else.

Thanks in advance. >Is there an echo in here? Surely this is because your VoIP provider is limiting your simultaneous connections. Have you asked them? j
