Re: [asterisk-users] Asterisk to asterisk t.38
Hi Bryant, The 1.4 box has two interfaces one with 202 ip and the other with 172 ip , the audio code has 172 ip and the ast 1.6 has only 172 ip. Any ideas ? Both the trunks have t.38 enabled on it. And the way we use fax is fax machine connected to ata which supports t.38 in both the ends.

Our audio codes gateway dumps into a 1.4 box and all faxes calls are then sent to either 1.6.x or 1.8.x boxes and then on to the final ata.

Ok, are both boxes connected to the same audiocodes gateway? Or are they in different locations? Can you try sending via regular POTS lines?

You don't say what's between the boxes as the medium over which the faxes are going. Try a fax between them without t.38 and see if it goes through. It might be a connection that is not reliable for any kind of faxing. That would not be an asterisk problem, it would be a faxing over a bad connection problem. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
