[asterisk-users] Asterisk 10 T.38 and 012 in Israel

[isrlgb at gmail.com]

Hi all

I'm trying to get asterisk 10 spandsp get faxes from 012 in israel (they use broadsoft switches)  using T.38 more reliable and would like to know if anyone knows of any changes I could make or ask them to make. 
As it stands now I get much more reliability receiving faxes with iaxmodem with no T.38 which is funny than when having asterisk receive using T.38 and if I try using gateway mode to iaxmodem then its even worse. 

I'm trying to test how much reliability will I loose when moving from a pri which is excellent but expensive to voip and T. 38.  How much tradeoff 

Thanks in advance,
Israel
