Hi, it looks likely I'll be installing a CME UC500 I'm looking for advice.
My customer currently has 3 FXO connected into his old PBX, generally I only use ISDN 2 with CME. What if any are the drawbacks of using FXO and not ISDN with CME? Will I still be able to use all the features of CME specifically music on hold and IVR, Hunt and Pickup groups etc? I also plan on using a SIP gateway to provide an additional line and to perform leased cost routing, would this be a problem with the UC 500?
In addition does anyone have relevant configuration examples for the UC 500 FXO model and BRI model?
