My telco is Orange in France. > > I'm using an old Asterisk 1.6.1 version there so I can't rely on > T.38/T.30 gateway feature at the moment. > > I said T.30 and not T.38 > Yes of course, I was referring to T.38 and completly forgot about pure G711 faxing with Asterisk sending T.30 fax to the Patton gateway,through SendFAX application. Please, apologize for forgetting this. > and the complete explanation would be rather technical. In essence a T.30 > fax with ecm enabled does not react nicely to certain signaling errors and > pertubations and this is easy to detect. > I'll try to to send a 10-pages long fax and report here my findings. > Most of the time I can guess what the problem is when I see the type of > error. Don't ask me how I learned this. Once you know what to look for, > Asterisk 1.whatever is very reliable as far as facsimiles go. > > jg > > -- > _____________________________________________________________________ > -- Bandwidth and Colocation Provided by http://www.api-digital.com -- > New to Asterisk?
