Patton configuration fixes

[Patch1]

Some updates I found useful to enable the ATA to be used with 3cx v18.

1. Advanced -> FXS/DECT -> Patton 2 Port FXS GW -> Provisioning Link: needs to be manually converted to https//.....:5001/...
2. The SN4112 / SN4114 have only one Ethernet port not 2 so the WAN configuration is ignores and the resultant LAN interface lacks a DNS and gateway
3. The "profile voip default" forces codec re-negotiation before the VoIP suppler receives a fax tone. Using the default Patton "ced net-side-detection" results in successful T.38 negotiation in all 3 VoIP suppliers I tried.

Tested with Patton Smartnode SN4114 FXO Firmware R6.11

To enable the Patton to access your time server (NTP uses the WAN interface by default in the Patton), a route to the LAN gateway needs to be added. To do so change this middle section of the configuration file from

context ip router

interface IF_IP_WAN
ipaddress dhcp
tcp adjust-mss rx mtu
tcp adjust-mss tx mtu

interface IF_IP_LAN
ipaddress <actual Patton IP> 255.255.255.0
tcp adjust-mss rx mtu
tcp adjust-mss tx mtu

context cs switch

context ip router

interface IF_IP_WAN
ipaddress dhcp
tcp adjust-mss rx mtu
tcp adjust-mss tx mtu

interface IF_IP_LAN
ipaddress <actual Patton IP> 255.255.255.0
tcp adjust-mss rx mtu
tcp adjust-mss tx mtu

context ip router
# Add a route to your LAN actual gateway eg if it is 192.168.1.1
route 0.0.0.0 0.0.0.0 192.168.1.1


context cs switch

To optimize T.38 protocol negotiation, update the fax T.38 negotiation refer to the
Software Configuration Guide. SmartNode Series. SmartWare Release 6.11 Section Configuring Fax Transmission pg663-668

Then change

profile voip default
codec 1 g711alaw64k rx-length 20 tx-length 20
codec 2 g711ulaw64k rx-length 20 tx-length 20
codec 3 g729 rx-length 20 tx-length 20
ced net-side-detection re-negotiation
fax transmission relay t38-udp
fax redundancy low-speed 2 high-speed 1

profile pstn default

To

# ced net-side-detection re-negotiation

Hopefully other find the hints useful.

Thank you for contribution and for sharing this information, I'm sure people visiting our forums will find this useful!

However, for anyone else reading this, I do have to mention that, since these settings deviate from the config generated by 3CX and have therefore not been tested by 3CX, we cannot guarantee normal functionality and will hence require the user to factory reset the device in question and reconfigure as per our guides should any problems arise and help/support is requested from 3CX.
