Hi

Faxes through a fax a server hylafax are not going. connection is going and the broke and fax not receive.
t38 enabled
provider use g729 codec (ullaw allow denied). in logs of asterisk i see allow codec maybe in this fault.
Also at office are used linksys spa 8000 (with option "use only g720 the codec") with analogue faxes all is good, but at reception earlier the same effect was (there is a connection then broke and fax not receive) yet have not changed FAX Passthru Codec with g711u on g711a and FAX Passthru Method:reinvite

You have no chances to get FAX working on g729 codec. Also, Asterisk/Hylafax (wich are the software that Elastix is based on) cannot use T38 faxing, so the only chance to get FAX working on a VoIP Provider is g711 (ALAW or ULAW) passthru, but this isn't a very reliable solution...

I'm sorry but this is the truth (I'm looking to get all working with T38modem, but, for now, it's very hard to do).
