(from uk.telecom, just to see if anyone here has tried it)

I am trying to use the G711 codec (the widest one) for faxing through
1899s VOIP service. Its not brilliant, even less than their PSTN
service for faxing.

Has anyone else tried it, and is there anything can be done to make it
useable? Mines a Sipura 2100 if that makes any difference. I think
VOIP faxing generally is a bit dead.

I was wondering if your tests were done with real fax machines or computer
applications.

Was ECM supported at both ends? (AFAIK most faxes dont use ECM).

Finally, I assume the transmissions took place at 2,400bps. If so, was this
forced or auto-negotiated?

Yes, Ive sent faxes from my fax machine attached to 1899ViOP, and the
recipients have received them OK. I know that because they have
replied, but to my normal landline fax number. (I dont yet trust
sipgate for a reliable incoming line).
