code is 1860* some firmwares this actually turns off the modem.
go off hook push program button should get beep, if not hang up then go hook push prog button again......no beep you didnt get into LOCAL programming.
DIAL 1860* should get beep hangup done. The modem in the Protel is set to 300 baud ......BUT I know expressent may be problematic if you don't allow 300 baud, - payphone_installer not sure if yours allows either. I never could get mine to connet either way with OOMA or Spectrum VoIP service period, to yours or anyone elses for that matter on the two VoIP services i have.
FYI 1861* is 1200 baud. (and some firmwares enables to max 1200 - some sets try 1200 then 600, then 300 automatically, however the calling computer must allow all, and i dont recall if expressnet allows auto baud or not been to long, payphone installer may know.)
If you dont care about rate tables for the diffrent bands, and just want to charge x for x mins the factory default program may be used, with some initial keypad programming on both 7000 and 8000 boards, but the 8000 board overall is the better board. the challenge is if you have custom firmware in your board, and you may not have the default rate table, local base programming ability, and many protels were OEMed and done for a specific third party, hence custom firmware.
payphone_installer can add his commentary as well, but its fairly easy** to make it charge for example 25 cents for all calls in all bands from the keypad. you CANNOT decide based on bands tho what to charge WITHOUT the rate table from expressnet being uploaded to the phone period, and newer area codes would definately not be defined in the base firmware so some number may not even be dialable youll get i think error 52 dont recall, all the error codes are in the pocket reference i posted for both 7000 & 8000 boards. **IF YOUR FIRMWARE IS CUSTOM OR LOCKED, YOUR OUT OF LUCK GENERALLY, but expressnet if i recal can reflash - hence send new firmware, but again if yours is LOCKED, its LOCKED it cannot be UNLOCKED.
you can validate you have the modem in yours as not all actually have a modem read the quick reference guide i posted for both 7000 and 8000 boards for instructions.
Side comments VoIP lines were NEVER intended for legacy data transfers, the propergational delays will cause problems period. For example call from your cell phone to you VoIP line and youll bee amazed in the delay. Modem technoligy from the 70/80s expects true loop start lines from the telco that have published expected standard to reliable transmit data, and the modems in that time were desigend specific to real bell specs, accounting for their propergational delay, which is NOTHING like what you'll experience with VoIP / Inet Phones, Cell phones etc. why you think 56k modems useless today, they will absoultly NEVER work on VoIP lines, not that any one uses it now anyways. Additionally, triditional ANALOG lines (POTS) are NOT the same as todays DIGIAL lines, yerteryears modems may or may not operate properlly. FAXs generally still work but at slower BAUD on todays VoIP lines, thats because the protocal has lots more error correction / detection in it. Alarm systems in general also work if the current-loop is correct, but thats even problematic for a 30 year old alarm system.
Another example of propergational delay, turn2 tvs on same channel, hooked to diffrent cable boxes in your house if you have digital cable, your hear delays between the diffrent sets.....
