Detail

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. 🙂

Requirements:

– This channel needs to work with a readily available Bluetooth USB dongle.
– It is desirable that this operate using the serial/headset profiles mentioned above, and be extensible to utilize the up-and-coming telephony profile.
– It is desirable that multiple phones can be paired with the Asterisk box.
– When controlling the phone via “virtual serial port”, AT commands shall be configurable separately for each phone.
– Each phone shall have a configurable pairing/unpairing event; that is, when a phone becomes visible to Asterisk, Asterisk can be configured to dial an extension or execute a script; ditto for the event that a phone leaves the Bluetooth network. This will allow automatic control of “home” vs. “away” modes, leading to more autonomous call-handling for home and small-office installations.
– This channel must be compatible with SonyEricsson T68 and T61x phones (& hopefully Motorola)
– The CID for incoming calls be passed to Asterisk. Not sure about name – there is an option to pass it on if the phone knows it, which probably would be nice.

In order to claim the bounty, the developer will have to show a channel which supports bluetooth, and is able to:
– Pair one or more cellular phones with a USB Bluetooth dongle installed on an Asterisk box.
– Generate an incoming ring event when a paired cellular phone is ringing.
– Allow routing this incoming call via bluetooth into Asterisk with full audio. (i.e. reach voicemail/IVR, or answer the call at an extension)
– Allow routing of outgoing calls through the cellular phone via bluetooth (i.e. Dial(BT/<phone>/<number>,<options>) )
