Just curious, is every processer for a CTX100 have different features depending on which software version you may have for it? I have the ACTU2AS V.2A for the processor with the SD card being R3.1 and I can not change the station type of an extension to SLT as I am trying to program my Teleco voicemail card. Is the version that I have not capable of doing SLT to program voicemail or is there something I need to set in Emanager to change it to allow SLT? Any advice would be awesome, thanks a lot!
