Netborder NCA Asterisk Support
==============================

Lyra AMD (Answering Machine Detection) is a patent-pending Answering Macine Detection engine 
that ensures fast and accurate automated call classification. 
It operates in SIP networks as a back to back user agent (B2BUA) 
which quickly and accurately determines the outcome of call attempts.

Asterisk Support

	Asterisk SIP stack needs to be patched in order to work with Sangoma NCA.

	Patch files are provided for each Asterisk Version.

	Asterisk 10  -> ftp://ftp.sangoma.com/lyra-amd/asterisk/lyra-amd-asterisk-10.8.0-v1.patch
	Asterisk 1.8 -> ftp://ftp.sangoma.com/lyra-amd/asterisk/lyra-amd-asterisk-1.8.16-v1.patch
	Asterisk 1.6 -> ftp://ftp.sangoma.com/lyra-amd/asterisk/lyra-amd-asterisk-1.6.2.24-v1.patch
	Asterisk 1.4 -> ftp://ftp.sangoma.com/lyra-amd/asterisk/lyra-amd-asterisk-1.4.27-v1.patch

    The Asterisk sip stack does not change very often, thus
    the above patch should work for all Asterisk subversions.
