Upgrade kit for the OpenCom 131

Internet telephony and convenient automatic routing 

Internet telephony has become a serious competitor for conventional fixed-

network telephony. The reasons are the growing number of broadband Internet 

connections, the introduction of a protocol for assigning telephone numbers to IP 

addresses, the wide range of gateways offered by various vendors and the 

proliferation of the SIP protocol. Voice quality and availability have long passed 

the stage of being experimental.

SIP Connect 112 upgrades Aastra-DeTeWe’s OpenCom 131 for Internet 

telephony. It consists of the M100-AT4 interface module and the external IP-

Gateway 1.

The intelligent routing selection of the OpenCom 100 enables three convenient 

methods of route selection for SIP telephone numbers:

»

automatic, using LCR

»

automatic, using a telephone book

»

manual, using a route code
