I have seen these but I wasn't sure if it would accept and pass the proper proticol for PMS integration.
If it does, then this is perfect. We are going to virtulize the Voicemail (4730) and needed to be sure we could connect with the PMS if the PMS could not be upgraded to accept an IP interface. Also possibly virtulize the 9500, with the same need.
It would be better to upgrade the peripheral but I'm looking for a "just in case" solution.
