There are two ways to use IAXmodem with static or dynamic libraries. If there is any machine in its version of spandsp or libiax2 different to those included with IAXmodem it is best to use static libraries (eg for distributions as trixbox preinstalled or similar) otherwise to make an installation dynamics.

Asterisk is an open source software PBX with almost all the features of commercial hardware PBXs. Deployable on Linux its one of the hottest open source products in the telecom market. Asterisk works
with IP telephony as well as legacy telephone systems. Asterisk can handle IVRs, voice mail etc with custom configurable modules. The bluetooth enabled PBX will be tied to a bluetooth mobile phone. The PBX can detect the proximity of the phone. When the phone is in range all calls coming on the PBX will be redirected to a normal phone connected to the PBX. But when the mobile phone is not with in range of the PBX, the calls will be redirected to the mobile phone, so that you wont miss any calls.
Note: Bluetooth phones can send/receive calls via AT commands on a “virtual” serial port, and then pass the audio data using the Headset protocol. We’d like to see support in Asterisk to send and receive calls with a Bluetooth phone. This would allow people to come home after work, throw their cell phone on a desk, and receive incoming calls to their Asterisk extensions. It’d also allow calls to be routed out via a cell phone, for cheap minutes or whatnot. One other option is to get two phones on a really cheap Family Time plan, and be able to route calls via an Asterisk gateway to your normal LD provider.

The company Atelier announced the successful completion of the port program Zfone to the platform Symbian (S60 and UIQ).
Recall that the program Zfone, originally developed by Philip Zimmermann (Philip Zimmermann), is intended to protect VoIP-through automatic encryption of communications packages. Zfone is integrated into the operating system and maintains a separate tracking VoIP-packages and their interception. Zfone is integrated into the operating system and maintains a separate tracking VoIP-packages and their interception. Working with voice data maintained at the level of protocol, so Zfone is compatible with any VoIP-applications that work with protocols SIP and RTP, and these applications do not need to further adapt to the Zfone.
