Can Asterisk 1.4.21 support 5 concurrent EXT

HI All
We are using Asterisk 1.4.21 and install 16 EXT. We found that, Asterisk are only able to send 1 EXT at a time,
only when this first EXT answered and next EXT will ring. It work out one by one. ( first come first serve)

is there any setting that we can make it few concurrent ringing to EXT

Thanks
Ben

Assuming that EXT means destination equipment address, list them in the Dial application call will &'s between them, for the extension number for which you want to ring them all.

Alternatively set up a ringall queue.

If this is a new installation, please note that version 1.4.x is no longer supported, even for security fixes.

Hi David

I think it is in extensions_macro.conf. if i want to enable 5 concurrent call at same time to 5 extensions. which one i need change ?

thx
Ben

Ask the person or organisation that wrote the dialplan.

Note that Asterisk reserves the term extension for things with the same value in in the first field of an exten => line. Using it for telephone instruments causes problems, particularly in a case like this where there isn’t a one to one mapping.
