[Asterisk-Users] Ring more than two isdn phones simultaneously
I am using a HFC-S card in nt mode with zaphfc driver to connect an internal isdn bus. I would like to signal an incoming call on, let's say, 4 phones. Right now I use: Dial(Zap/g1/21&Zap/g1/22&Zap/g1/24&Zap/g1/23&Zap/g1/29,,t) where g1 are my two isdn channels provided by HFC-S card an the 21,22,etc my internal numbers. When the command is executed however, only the first two specified phones ring. Etc. with the first channel 21 ist called, with the second 22. How can I get asterisk to signal to all phones with just one isdn channel? I am trying to duplicate the setup I had with my old isdn pbx with did above trick just fine... Maybe somebody can help me configure asterisk appropriately? Cheers, Arik PS: I gave following a try but without success: Dial(Zap/g1/21-29,,t) Dial(Zap/g1/21+29,,t)

how many connection do you have from your asterisk to the old pbx? i think on 1 ISDN connection its only possible to let 2 phones ring, because 1 ISDN 2 channels...

If this is a limitation of asterisk, where is it located? In the chan_zap module? In zaphfc? I.e. would it help if I switched to mISDN?

This is a limitation in Asterisk, not ISDN. Asterisk reserves a B-channel for each destination at the time of the CONNECT message. In the isdn world it is common to not actually allocate a B-channel until it is needed to carry audio. This also prevents Asterisk from letting the upstream switch select the B-channel on outgoing calls to the pstn. Asterisk is written this way since it uses the audio channel as the fundamental unit, with the D-channel as carrier of signalling for the individual B-channels. Another way to view ISDN is to consider the D-channel the fundamental unit, which can carry several audio streams as a side effect of the signalling. The first viewpoint resembles the traditional view of telephony as individual circuits, the second resembles the ISDN/SS7 view of the world. Changing Asterisk to be more ISDN-like is quite a lot of work.
