I finally have the lines registered through the GXW4104. I can make inbound and outbound calls. But heres the catch, If I set the Individual lines in the "Route Inbound Calls "In or Out" office Hours" to this selection: Connect to Extension. I get the voice mail. Connect to Digital Receptionist, I get a quick flicker on the Line Status indicator and then no connection or perhaps no audio. The Server Status message is as follows: 1st CallConf: onincoming: Incoming cal from Ln:10000@GXW4104 to sip:firstname.lastname@example.org 2nd Straitinout:nCance: Call from Ln:10000@GXW4104 to Ln:10000@GXW4104 has been terminated. Any Ideas ? Also How does the music on hold function? can the file be substitued? It is grayed out on my browser.
