HI Gordon
Yes you should move the user-password if you can. You can use $password to receive the sark system generated random value.
Don't know the Oscoms but you can add support so that SARK will recognise them by creating an "mfgmac" entry in the database. Just open the database and have a look. It uses the first three bytes of the MAC address to recognise the different phone types.
00:01:E3=mfgmac|name|Siemens
00:04:13=mfgmac|name|Snom
00:04:F2=mfgmac|name|Polycom IP X01
00:08:5D=mfgmac|name|Aastra
00:0B:82=mfgmac|name|Grandstream
00:0E:08=mfgmac|name|Linksys
00:11:5C=mfgmac|name|Cisco 7960
00:14:A8=mfgmac|name|Cisco 7940
00:15:65=mfgmac|name|Yealink T2x
You can just add one for Oscom. You'll also need to add an entry in Devices but you are already an expert in that.
Best
