One was acting as a network (master), the other as a subscriber (slave) (for timing). wrote two dialplans, one for each machine, that would answer an incoming call on one dahdi line, and call to the next numbered line on the other machine. The other machine was similarly outfit. I'd define the extension for the first line on the t1, and call it with any phone you desire. That call will cascade into 23 separate interlinked calls. If you are clever, the last call in should dial another real phone you have on-hand. You get the picture... right? Phone A dials the exten to call the first exten on the other machine. The dialplan should use the first channel on the t1 to place a call to the first exten on the other machine. On the other machine, the incoming call on channel 1 is answered, and then a dial to the second extension on the first machine, over the 2nd t1 channel. The first machine answers, and uses the 3rd channel to call the other machine.... and so on till all channels are being used. The last exten answers and dials a phone (dahdi or SIP, no matter) that you pick up. Such a looped call should probably be awful, but it's going thru 23 t1 channels! If you have two t1 interaces in a single card (or two cards), then you do this on one machine. Another approach: set up equal numbers of FZO and FXS lines, and similarly loop s single call thru all the channels.This would require just one machine. Other approaches would involve running multiple threads to call an extension and then hang up and repeating this over and over again on all channels to ascertain the load placed just by call setup and tear-down. This kind of load is different than when all lines are just shoveling data back and forth. Watch your load averages, your %cpu, your swap, etc, as the tests are in full swing. murf > >> -- >> _____________________________________________________________________ >> -- Bandwidth and Colocation Provided by http://www.api-digital.com -- >> New to Asterisk?
