I have two asterisk box’es. On first I have TE412P card, chan_ss7 ans res_fax. On second I have res_fax. Those two boxes are connected via TDMoE and chan_dahdi (euroisdn).
When I try to receive fax on first box it works fine (100% faxes are fine), but when the fax goes from chan_ss7 on first box and than to chan_dahdi (via TDMoE) on the second box, about 60% of faxes is failed.
What can be problem?
