Minimum firmware version for M73xx phones on BCM 50

[telecom116]

Is there a minimum firmware level on M7310 or 7324 phones to work on a BCM 50 system? We are replacing CICS and MICS system this summer with BCM 50s and I thought I saw somewhere a minimum software version requirement. Most of these Norstar systems have been around since the mid 90s.

Release 18 if you want the "use set volume" feature to work.

Also, I don't think the old 7310 BLF modules work on the BCM 50.

Thanks! With us basically keeping old Norstar phones at 10 locations with the new BCM 50 installed I didn't want to find out the sets wouldn't work.
