PCTel Inc. has developed a VoIP-Enabled Roaming Client, which, when deployed with a compatible server, permits users to make and get calls using the same number on cellular and IP networks.
Out of the gate, the roaming client operates over GSM and Wi-Fi networks. Later releases are expected to support CDMA standards.
The product supports connection management, profile management, Wi-Fi hot-spot authentication, and 802.1x/WPA security on wireless networks. It also has a Voice Dialer that operates on both cell and IP networks.
One of the benefits the client has is that users have just one interface for sharing contacts and getting call histories.
The product will be available in the spring. The company didn't disclose pricing.
