backport IAXVAR to asterisk 1.4.44

Hi, I need IAXVAR functionality in Asterisk 1.4.44 . This was only added in Asterisk 1.6 . You can either backport from Asterisk 1.6 and modify chan_iax2.c (and the additional files), either you can try to make this patch work: [login to view URL] (Patch was made for Asterisk version 1.4.23 ) Should be one hour of work for a decent C programmer. Please compile , start asterisk and make sure you can use command core show function IAXVARs and upon using it it won't crash the system (i can help out with testing if need be) If you have no knowledge of Asterisk and what it is, please do not bid!
