Received an unsolicited call from a gentleman from this number.  It was difficult to understand his name in the message he left.  Caller ID gave the company name as "Revgen," but the caller said he was from Citrix.  He didn't say why he was calling, just "reaching out" and wanted me to call him back.  No thanks.

This number called the office this morning before anyone arrived, but there was no message waiting.

If this was yet another number for Citrix, they appear to be to persistent for their own good. They've also called us using 919-745-6193 and 919-582-5507 during the summer. Each time they've called, I've asked them to put us on their Do Not Call list.

if they do call again, I might have to ask if they understand English, and if so, how come they ignore our requests to stop calling?

I received a call from this number.  Caller claims to be calling from Citrix wanting to "reach out" (ugh--business marketing new-speak).  I have no Citrix products at all.
