I am actually using Fax Pass-through and I am having few problems.
Is fax mode a better solution?
Also, what should be the input and output level of the FXS port?
I am on the same VLAN, network is good and my GW is in MGCP and ATA is in SCCP.
Super G3 fax is disable and ECM is off. Soemtimes I can see retries on the fax.
