I have completed my latest 3CX installation for a new customer with one outstanding piece of config. I have just received the Patton 4114 that I want to use with the customers only PSTN line/Fax line as a backup in case their ADSL or VOIP provider is offline. The PSTN line is currently used as the FAX line and is the same line that the ADSL uses. I was of the understanding I could use this Patton 4114 to share the Fax line and route any inbound voice calls to 3CX and route any inbound faxes to the fax machine. I was told this was possible and didn't give it any more thought until I just unboxed and connected the 4114. I wish to use this single PSTN line as an emergency fall back for a single concurrent call whether that be a single inbound or single outbound call. Does anyone have any experience with the above scenario. I ran the Add Gateway Wizard which seems to want to connect 4 3CX extensions to the 4 ports on the gateway even though I only wish to use one. I generated the config file and uploaded on to the 4114. I now cannot see the gateway in the VOIP/PSTN gateways list, it is still empty. Does anyone have any experience with doing what I am trying to achieve. Any advice/assistance would be greatly appreciated. This is my first PSTN Gateway that I am attempting to setup, all setups thus far are straight SIP setups. It would even be fantastic if 3CX could accept and save the faxes rather than them being diverted to the traditional fax machine, however I don't know whether that is possible. This customer requires a fax for legal purposes.
