(The comma provides a 2 second delay for dial tone to return)
If it still doesn't work, set both of the QOS values in the hub to 0.
Go to the lounge and disable the connection tone as that may confuse the modem handshake.

The connection done is irrelevant for outgoing fax. It will not be played when your fax machine (or phone) is connected to a remote fax (or phone).murphy wrote:Go to the lounge and disable the connection tone as that may confuse the modem handshake.
It is only played to callers when their call is connected to your system, so it could potentially confuse the handshake during an incoming fax. However, as the originally poster, and several others have noted, there never has been an issue with incoming fax transmissions.

I fax, using a simular HP fax machine, using *99 -one pause- 1-xxx-xxx-xxxx without fail. Two pauses won't work for my HP machine.bw358 wrote:I am using the *99 and 2 spaces before the phone number I am faxing but I am still getting error messages. Any other ideas?

Factors That Influence Success or Failure of VOIP FaxingThe best tip I can offer is to reduce your fax transmission speed to 9600 bps to maximize VoIP fax success rates. The faster one tries to send a fax, the more likely it is to fail on a VoIP connection. That's because more fax data is jammed into each transmission second while the digital on/off signaling rate remains constant. More data gets lost as faxing speed increases, until data loss exceeds the intelligible threshold and the receiving fax device aborts the transmission, effectively saying, "I don't get it, try again."
Also, turn off Error Correction mode on both fax sending and receiving machines, if it is on. VoIP has a fairy high signal noise level due to jittery instabilities in the connection. This causes many false positives for "errors" when Error Correction is enabled, which can abort a transmission unnecessarily.
Use a VoIP service provider that supports the T.38 protocol; just ask or check the service's detailed specifications online. T.38 was developed specifically to improve the success rate and quality of faxes transmitted over VoIP. Note that it just improves, it doesn't perfect.
