So I have an interesting issue that I can't seem to figure out. Have an IP Office v 8.0(44), and have a few extensions then when a call connects the number 9 key does not get recognized. I can dial out, 9 1 XXX XXX-XXXX, with out issue. Once call connects 9 will no longer tone. If I move the handset to another location on the BIX the 9 issue resolves itself. The wiring looks correct in and out of the BIX so I feel it might be port related on the system. Any thoughts?
