Just imagine: your new system telephones simply connect up to your computer network and your building needs no separate telephone wires. Or your regional representative at the other end of the country is an internal(!) subscriber in your telephone system at the company headquarters and his availability status – whether he is making a call, is receiving a call or has activated call forwarding – is indicated on the LED displays of other system telephones. He can call from his office via the headquarters system and use all its cost-saving functions while his telephone number as indicated to his business partners is that of the headquarters.

With the same design and range of functions as the COMfortel 2500 for ISDN, our new IP system telephone is the right choice for all those who want to invest in new technology for the long term and always be up-to-date for future upgrades. The COMfortel VoIP 2500 AB and Auerswald's LAN-enabled telephone systems provide the harmonious basis for you to benefit from IP telephony.

The COMfortel VoIP 2500 AB is more than a telephone: all you need is a USB momory stick to use the integrated answering machine COMfortel Voicemail. It takes messages in your absence, records conversations or greets your callers with different messages depending on the time or day or caller number. An USB stick with 2 Gigabyte memory is included, and the voicemail function is available without any additional activation.

And here is a little bonus for frequent callers: COMfortel VoIP 2500 AB lets you connect a wireless headset (DHSG). Those who have the convenience of a self-powered LAN can do without an additional power supply thanks to "Power over Ethernet" (PoE). And if the network port is already occupied by your PC, simply route the PC's network connection through the telephone, with its two Ethernet ports.

The telephone's modular concept lets you add up to three COMfortel Xtension30 modules for extra function keys*. You can fit them on either side of your telephone. With all modules fitted, you have 105 function keys available. Each key has 2 levels offering a total of 210 functions available upon key stroke.

The COMfortel VoIP 2500 AB is available in the colours black, dark blue and light grey (white).
