IP Office ISDN30 Card

An IP Office ISDN30 card is optional extra IP Office hardware that enables your IP Office telephone system to connect through ISDN30. The PRI module connects iSDN30e (European Standard) digital Channels to your Avaya system. The minimum number of channels is 8 and this can be increased up to 30 without the need for extra hardware or installation. The advantage over tradition analogue lines is an improvement in speech quality and you can have multiple numbers sharing the channels. The iSDN30e can be configured with Direct Dial In (DDI) which are bundled in multiples of 10 consecutive numbers allowing your employees to be allocated their own personal number without the extra cost of line rental. Your clients can also be directed seamlessly to the correct department or user without the need to go through a receptionist.
