Expansion Module firmware support



I am running

UC Software Version

Updater Version


I want to get the em1 expansion module working correctly with a vvx 500 phone in a Lync 2013 environment. I have found conflicting firmware reports.


4.6, 4.7 and 5.1 and later

As seen here,


4.6, 4.7 ONLY

As seen here,


So which is it?


Note: I do not have an "EM Directory" tab from within my phones web server. It is nonexistent. 


Also, I am unable to revert my vvx 500 phone back to ANY version from it's web server. The phone reaches out and finds other versions as it should, but when I choose one to revert to, any one as I tried them all, it gives me a notice stating that I need to agree to terms and then says:


The phone will reboot and be updated only if the software you

selected is compatible and different from the currently

installed version.
Note:The phone has either rebooted/restarted due to

configuration changes. Please refresh the browser after the

phone startup.



It never updates.

I can not seem to get any other version installed on this phone. What can I do about this?


Thank you

Re: Expansion Module firmware support

Hello DonovanD,

I have updated the FAQ post and please ensure you always check the Software Release notes accompanying new releases in regards of details what is actually supported.


Only if the Paper Expansion Module is connected to a Phone the Menu appears as it is used to print the labels.


In regards being unable to install other versions please check the logs or any error messages.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards
