To use a Patton SmartNode like an ATA bank you would register each port separately with its own identity/number. This is particularly useful not only for registering analogue handsets to SIP but also when using a VoIP gateway to trunk a traditional analogue PBX to SIP.
Use the sample below to build you configuration but searching & replacing the appropriate sections in your favorite text editor.
#
# SN4114/JS/EUI - DHCP client, registering to a generic ITSP.
# 1. Search & replace[MyITSPAccount1], 2 3 & 4 including the braces e.g. [MyITSPAccount1] becomes 02811111111,[MyITSPAccount2] becomes 0282222222 etc... then search & replace [MyITSPPassdword1], 2,3, & 4 as previous
# 2. Search & replace the SIP registrar [sip.MyITSP.co.nz] with your ITSP registrar (we are making an assumption that registrar, proxy etc are all the same name)
# 3. Save the text file & import to the SmartNode via http://[SmartNode_IPAddress]/imp-cfg.html e.g. http://192.168.1.20/imp-cfg.html
# 4. Restart the device (resist the urge to 'save the configuration' while rebooting
# 5. Check the bootlog for any errors (http://[SmartNode_IPAddress]/rpt-bl.html)
