Hi,I am attempting to make about ten calls simultaneously and intermittentlyget 'SIP/voipprovider is circuit-busy' followed by 'everyone isbusy/congested at this time" I am not sure if this is related to my bandwidth to my voip provider, aconfiguration issue or something else. Has anyone seen this before and have any suggestions. Thanks in advance.

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.

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

Thanks for the reply and apologize for the double post. My original post
landed in another thread and thought it may have been missed...
I questioned my voip provider before posting and they told me they have
other asterisk customers that are making hundreds of simultaneous calls
without problems with the same account type that I have. They indicated that
they do not limit my simultaneous connections. I am now going to have them
trace my connection but hoped to learn of a possible configuration setting I
could check first.
Thanks again for the help.

The message you are hearing is coming from your asterisk server, and it is
because there was either no response to your call attempt or your call
attempt weas refused by your VoIP provider. In the "no response" scenario
it may be because you are strapped for bandwidth, but if you were THAT
strapped you would have many additional problems, and the calls that were
going through would have serious audio problems.
So I would focus on the idea that your VoIP provider is refusing the calls
that are failing.
You could prove this with a packet trace. Use wireshark/tcpdump to
capture your attempts and see if you can find the session that is refused.
You will either see the refusal come back or the request timed out...
Good luck,
j

Couldn't he also just do a "sip set debug" to view the responses coming
back?

If none of the calls were going through then that would probably be an authentication issue. If some of the calls are going through then you should check with your provider. I have ran into this issue when one of my providers failed to allocate enough channels to accommodate my call volume. One provider required that send over some documentation before they would allocate more than 5 channels. If I setup a PBX for another company then I always ask for 20% more channels than they need.
Occasionally a provider's servers fail to update their channel database when a call is terminated (leaving their system to believe there are less channels available than there really is) or their server fails to detect the call has terminated leaving a channel in use until it times out.
If you have more than enough available outbound channels then my only other thought is a DNS or NAT issue. I forward ports 5060-5080 and 10,000-30,000. I also ran into this problem when the DNS server's forward lookup zone was improperly configured causing delays returning the provider's IP address. Sometimes it would return the IP address in time and other times it would timeout waiting for the IP causing the calls to fail.
