I plan to put two MVP130’s onto a Magix switch and I want to know if the message waiting lamp will light on the remote site?

For the message waiting light option, the E&M interface needs to be used. The MVP130 only has FXS and FXO interfaces so it doesn't have this option. The multiport models such as the MVP210, MVP410 and MVP810 do have an E&M interface and support the message waiting lamp feature.
