ISDN30 for dialers
In the UK we can get ISDN30 cards for PCs. The ISDN30 is similar to T1 but with 30 channels. Can the application dial 30 calls at the same time.
Yes, Voicent software can dial simultaneous calls. Actually the number of simultaneous calls is only limited by hardware and bandwidth. Our call center customers routinely use more than 30 lines for calls.
Voicent software will not directly use the ISDN30 cards. But you should be able to setup a PBX system, such as the free Asterisk PBX, to use these 30 lines. You can then create SIP extensions for the PBX. Once you have these extension setup, you can configure Voicent software to use these extension to make calls.
