However, not only the recipient can be a mobile phone. VoIP-enabled cordless phones are great alternatives to VoIP Adaptors, and a particularly good option if your existing handset is in need of replacement. For ultimate flexibility and freedom, these models let you make VoIP calls from anywhere in your house or office. There are several methodologies by which a mobile handset can be integrated into a VoIP network.

One implementation turns the mobile device into a standard SIP client, which then uses a data network to send and receive SIP messaging, and to send and receive RTP for the voice path. This methodology of turning a mobile handset into a standard SIP client requires that the mobile handset support, at minimum, high speed IP communications.

Another implementation of mobile integration uses a softswitch like gateway to bridge SIP and RTP into the mobile network's SS7 infrastructure. In this implementation, the mobile handset continues to operate as it always has (as a GSM or CDMA based device), but now it can be controlled by a SIP application server which can now provide advanced SIP based services to it.
