We have 3 locations being serviced by the same Audix system. When accessing the main site's main # and going through "dial by name", we are good on 2 of the sites...but the 3rd one only sends the call to the person and not on to their voicemail...instead it sends the call to the guest access # (or "enter the extension you want to leave a message for" prompt). Site 3 is an S8300 w/CM3.0.1 and the main site is an S8710 w/CM 3.1.1. The other ok site is a Prologix V9. Only other difference is site 3 gets its dial tone from the main site. I made several changes but get the same result. Ideas? Anything w/regard to QSIG?
