•Set your FAX device to 9600 baud. Higher rates are not "officially" supported by TBB.
•Set your TBB Web Portal - Options - Call Quality to "High Bandwidth Voice / Best Quality"
TBB Faxing is only supported officially at 9600 baud since there are technical limits related to bandwidth and jitter. However, depending on the quality of each user's LAN and ISP connection, TBB faxing can work at 14400 or more (some users report using this successfully).
Following is "snickerdo"'s tip that helped him and others with faxing more than one page:
A DSL filter is meant to remove the DSL signal from a phone line. However, used in this way with the DVG, it probably removes high frequency noise due to jitter (etc), from the fax line, thus perhaps making it more stable.
Put a DSL filter on your fax machine. Yes, a plain ol' filter used for the same DSL that Bell sells. They can be purchased for about $5, or you can get them for free if you have a Sympatico DSL High Speed account. In other words, place a DSL filter on the Line 1 port of the gateway, and split it from there as needed.
If you have trouble with FAXING, run the Primus VoIP Test. At the end of the test, provide the ticket # to Primus TBB Technical Support who can sometimes help to resolve the issue.
A Primus comment on Faxing:
Note that faxing is considered a best effort service over IP. (IP itself is considered best effort). With the nature of the underlying protocols and codecs supported by most major VoIP providers, it's currently very susceptible to packet loss.
