PSTN Voip Gsm Gateway , Voip Fxs / Fxo Gateway MWI T.38 Fax Relay DID Echo Cancellation
Description:
OFS- CG4 Analog Telephone Adapters (ATA) series offers high quality low- density access devices used
in residential, SOHO and mobile office VoIP applications. It provides reliable, low- cost, and flexible means to deploy converged communication solutions for network operators and enterprises. OFS- CG4 series
can be configured as either 2-in- 1 with connections to Ethernet and analog phones, or 3-in-1 with connections to Ethernet, analog phones and CO lines.
Consisting of 3 models, OFS- CG4 series is a desktop and wall mountable. The highly compact hardware with a ARM9 400M CPU supports the Linux kernel and the application software which inherits from the OPTFOCUS famous MX gateway design, delivering stable performance, high interoperability and compatibility, and rich features. OFS- CG4 series is a cost- effective entry level VoIP device with the capability and quality seen in expensive VoIP equipments.
