I'm not sure what that all meant, since we already had the DIDs for over a year. They said they had to port it over from Verizon to L3. It took over a month... and yet we still can't get an inbound fax through. Anyone know of a faxing service that uses t.38 that we can use to test faxing to ours? Unfortunately, we can't use our internal fax since our ata doesn't support t.38. > > Ly Tran > > From: [email protected] [mailto: [email protected]] On Behalf Of Tony Graziano > Sent: Thursday, July 21, 2011 2:27 PM > To: Discussion list for users of sipXecs software > Subject: Re: [sipx-users] T.38 Faxing on SipX 4.4 Setup > > Eh.
