We have some 411-5nH boards running 5.18 with a MC8705 card.
Is it possible to send a SMS from the card using routerOS? How about while a call is in session?
I played around but wasn't able to send a SMS, but I'm not sure of the SMSC (i found a few by googling) or channel (4 was busy so I used 3, which is the 'info' channel).
If it's possible I will investigate further with our SIM provider, to find out the correct SMSC.
