Your advantages in detail

Whether it is operating as a hybrid VoIP telephone, either as a system telephone for our IP PBXs or as a standard SIP telephone for a software-based PBX or IP Centrex solution, the COMfortel 2600 IP keeps you in command of any situation, using the keyboard, four-way navigation key or, like a smartphone, via the touch display.

Its integrated telephone book has space for more than 2,000 entries, and, if required, your e-mails, calendar and contact data can be synchronised efficiently with the cloud. Using a VPN, you can even connect the telephone to a remote ITC PBX from home, and use its functions. SIPS and SRTP ensure no-one can listen in when you're calling over the Internet.

The answering machine can be enabled with a standard SD card, and a separate interface that supports cordless EHS devices makes hands-free telephoning easier and more convenient. If the 15 individually programmable keys are not enough (for line busy, destination, system and SIP functions), you can program even more functions directly in the touch display or connect up to three key extension modules.
