Strange that Vonage would neglect their own Vonage branded ATA in that fashion (especially since on their support pages they no longer seem to advise using *99 for fax transmission for any current ATA). The original purpose of using *99 was to set the bandwidth to maximum on early models of some Cisco/Linksys ATA devices.
Later models and later firmware releases did that automatically when a fax transmission was detected by the ATA. If you order a dedicated fax line, that line is automatically provisioned for maximum bandwidth, so even with an older ATA, the *99 would do nothing when using a dedicated fax line (or a voice line with bandwidth set to maximum bandwidth).I do not see anywhere in the OP's posts saying that the V-Portal was the ATA in use, so even if using *99 is an official undocumented requirement for that ATA, it might not apply to the OP (it certainly does not apply to my setup). A good rule of thumb is to offer advice that says "this may help", but don't assume that what works for you must be done and/or will even work for everyone else.
