Two AltiGen products are approaching end-of-life and will not be tested or supported in future versions of MAXCS (those versions released after MAXCS 6.5 Update 1):
ALTI-IP600: All models of IP600 VoIP phones
ALTI-TTT1: Older T1/PRI boards (identified by “TT1” in the serial number, for example, (124A5TT1S1752)
MAXCS 6.5 Update 1 is currently the latest version of MAXCS and does fully support the IP600
phone and the older T1/PRI boards
Also, AltiGen is discontinuing the ALTI-OFFICE2G and ALTI-SYSTEM2G series chassis.
The ALTI-MAX2000 and ALTI-OFFICE3G/SYSTEM3G are the recommended chassis upgrade paths.
