asterisk users - Mar 2005 - Asterisk Manager API - multi "Originate" calls

Been researching connecting over TCP\IP to Asterisk Manager API to initiate
several concurrent calls to dial out. Prefer not to generate ASCII .call files.

Question : I read in places that you use "originate" command and wait
for an event back, does that mean you cannot place another "originate"
until the event comes back ?

Is it true that multiple API connections to Asterisk Manager API will crash it
(thinking of alternative way to crack the nut)

All help would be welcome - thanks

<< read in places that you use "originate" command and wait for

Not in my experience.  Originate will not send an event to the caller
until either the intended caller (that is the extension used in
Originate) has picked up their phone or a timeout occurs because the
intended caller does not pick up their phone.  You can send as many
originate requests as you like but they will fail if more than one uses
the same extension at the same time.

 

The issue you will face is determining which event generated by Asterisk
belongs to which origination request.  For this reason, the Manager API
allows you to specify an "ActionID" on any command. An ActionID is any
string of characters that you use to uniquely identify each command use
issue.  Asterisk will include the ActionID with each related event so
you know which events to respond to and which to ignore.  You will see
many events generated by Asterisk only some of which will relate to your
command.  The others will be events that Asterisk raises (for example
when a phone registers) or events in response to commands issues by
other Manager API users and at the command line.

 

Take a look at Nicolas Gudino's Flash Operator Panel (www.asternic.org
<http://www.asternic.org/> ) as it used the manager API extensively
(albeit through a proxy) and will typically make many requests via the
Manger API.  

 

<<Is it true that multiple API connections to Asterisk Manager API will

Again, not in my experience.
