Asterisk with PSTN

Dear Asterisk Users,

Is it possible to make 100 outbound concurrent calls on one pstn line connected to asterisk.

what would be a possible option to make 100 outbound concurrent calls using PSTN line with ASTERISK?

Please Help me

Thanks in Advance.

Depends on what PSTN line you want to use:

analog PSTN line - 1 concurrent call
ISDN BRI - 2 concurrent calls
ISDN PRI (E1 - 30 concurrent calls, T1 - 23 concurrent calls)

If you want to have 100 concurrent calls on the Asterisk server, use multiple E1/T1 uplink connections or use a SIP/VoIP provider who allow higher concurrent call loads.
