Generating faxes on the first and take them on the second, faxes are 100%.

2) Asterisk 10.1.3 - sip,g711a,t30 - Asterisk 10.1.3 (circuit through the pri)
Asterisk 10.1.3 equiped with 2 span (pri). Generating faxes on the first and passing through the pri take them on the second, faxes are 100%

3) Asterisk 10.1.3 - sip,g729,t38 - Asterisk 10.1.3 (circuit through the pri)
Asterisk 10.1.3 equiped with 2 span (pri). Generating faxes on the first and passing through the pri take them on the second, faxes are 30-40%, sometimes above.

In what may be the cause of the problem ?

Thanks for your comments. This does not appear to be a bug report and we are closing it. We appreciate the difficulties you are facing, but it would make more sense to raise your question in the support tracker, http://www.asterisk.org/support.
