The GXV3005 features an additional FXO port and is part of the GXV3000 IP video product line series. The GXV3005 features the same design and all of the functionality as the GXV3000 model, but it comes with the advanced versatility of an FXO PSTN line port, which enables customers to receive both video telephony service over an IP network and their home land-line.
One thing I like about Grandsteam is they follow industry standards, such as SIP, but also H.263 & H.264, so in theory their video phone will work with other H.263/H.264 compliant video phones.
The GXV3005 is based on the same feature set as the GXV3000, including a 5.6 inch TFTP adjustable LCD screen, a VGA camera which allows nearly all viewing angles, support for real-time high-quality video (up to 30 frames per second) using H.264/H.263 video standard at bandwidths as low as 32kbps and up to 1Mbps. The additional FXO/PSTN port supports calling over and between two networks (IP and PSTN network) from a single phone and offers both a layer of security and back up for IP video phone communication by providing the option of a PSTN life line.
