Hi. Thank you for your reply.Hi Shark8000,
This is an un-supported gateway with 3CX as you are most likely aware:
https://www.3cx.com/voip-gateways/
If you want to get this working easily with 3CX you will need to have a custom template for the device.
I have one for the SN43xx range of FXS channelbanks for v15.5 of 3CX which you can adapt. PM me if you want this (I have a full guide written also).
The configuration for the channel bank devices are not much different from the standard "supported" models once you have this template, other than you have more extensions: https://www.3cx.com/voip-gateways/patton-smartnode-sn4112-fxs/
In short you will need to configure the extensions on 3CX that you require to be used as your FXS extensions.
The custom template needs to be placed here within the server:
Windows: C:\ProgramData\3CX\Instance1\Data\Http\Templates\fxs
Linux: var\lib\3cxpbx\Instance1\Data\Http\Templates\fxs
Once the template has been included in the correct folder it should now appear as an option in 3CX under the FXS/DECT section (Patton). A reboot maybe required for this to show.
You can then add these extensions under the FXS/DECT section in 3CX and load the provisioning link into the Patton.
As it is a channel bank the device should require a high density RJ21 cable also - have you got one of these ?
Founded in 2005, when VoIP was an emerging technology, 3CX has gone on to establish itself as a global leader in business communications.
