If it would be of use in FOP2 development, I'd happily contribute a SCCP deskset for testing, etc. My intention is to keep our SCCP extensions on CME, but support in FOP2 for SCCP presence info is quite desirable.
SCCP registration/presence support was tweaked/fixed already. You can install FOP 2.27 and see extension buttons greyed out if they are not plugged in/registered into asterisk. I do not have any idea on how to integrate that with CME? I do not think FOP2 will work besides or outside the asterisk manager (AMI), as FOP2 does not talk sccp, it just talks to asterisk via AMI.
Best regards,
