There is a configuration variable that allows you to tune +this to your needs. e.g. in cellphone.conf + +[dave] +address=00:12:56:90:6E:00 +port=4 +context=incoming-mobile +dtmfskip=50 + +change dtmfskip to suit your phone. The default is 200. The larger the number, the more chance of missed DTMF. +The smaller the number the more chance of multiple digits being detected. + + +Debugging :- + +Different phone manufacturers have different interpretations of the Bluetooth Handsfree Profile Spec. +This means that not all phones work the same way, particularly in the connection setup / initialisation +sequence. I've tried to make chan_cellphone as general as possible, but it may need modification to +support some phone i've never tested. + +The RIM Blackberry 7250 works extremely well. So does the LG TU500. + +Some phones, most notably Sony Ericsson 'T' series, dont quite conform to the Bluetooth HFP spec. +chan_cellphone will detect these and adapt accordingly. The T-610 and T-630 have been tested and +work fine. + +If your phone doesnt behave has expected, turn on Asterisk debugging with 'core set debug 1'. + +This will log a bunch of debug messages indicating what the phone is doing, importantly the rfcomm +conversation between Asterisk and the phone. This can be used to sort out what your phone is doing +and make chan_cellphone support it. + +Be aware also, that just about all cell phones behave differently. For example my LG TU500 wont dial unless +the phone is a the 'idle' screen. i.e. if the phone is showing a 'menu' on the display, when you dial via +Asterisk, the call will not work. chan_cellphone handles this, but there may be other phones that do +other things too... + +Important: Watch what your cell phone is doing the first few times. Asterisk wont make random calls but +if chan_cellphone fails to hangup for some reason and you get a huge bill from your telco, dont blame me. + + +Feedback, Support, Please can you make Cell Phone X work... etc :- + +email me at david.bowerman at gmail.com or dseeb_ on #asterisk & #asterisk-dev irc.
