The 2CanCall system can connect to a variety of landlines in different ways. We recommend that you have a connection to at least one landline for emergency purposes and should any IP lines go down you also have a backup route for dialling out.
Analogue lines Using an internal card, or external gateway box, we can connection to standard analogue lines, usually in multiples of 4.
ISDN2 Internal cards can be used to connect to ISDN2e lines. Usually 1 card per ISDN2 wallbox External gateways are also available and connect to either 2x ISDN2e or 4x ISDN2e giving a maximum of 8 voice channels per gateway
ISDN30 Internal cards are normally used to connect to ISDN30 (E1) lines. These give maximum of 30 voice channels per card, and each card connections to 1x ISDN 30 connection. You can use multiple cards or multiple interfaces to connect several ISDN 30's together, for example it is not uncommon to have 4x ISDN 30 cards to give 120 voice channels in total.
