Asterisk settings for BrainTEL

Quick Instructions on how to setup Asterisk for BrainTEL

BrainTEL only uses the g729 codec, make sure you have the g729 codec installed.

Replace 210XXXX with your BrainTEL number in the following examples:

SIP.conf

[general]
register => 210XXXX:<password>:[email protected]:8891/210XXXX

disallow=all
allow=g729
allow=ulaw
allow=alaw

Add allow=g729 immediately following disallow=all, for some reason BrainTEL SIP negotiations fail, if g729 is not listed as the first codec.
