I have an IP406 that is connected to a remote Audix voicemail system. The link is via a T1 and is set up to do Qsig. The voicemail works fine for the users at the main IP406 site, but I have 4 analog opx phones that feed off of the IP406 and go to a different remote location other than the Audix site. The message waiting light does not work on the OPX phones, which we knew it wouldn't but is there a way to give them an audible indication when they have voicemail??? I tried turning on Voicemail ringback and it didn't seem to work...the IP406 is 2.0 any ideas would be appreciated.
