Update on migration from PBX to Voip

unknown

Whoever has been following me and giving me tips on setting up cme in the office to a sip trunk. Just wanted to give the update migration completed. I figured out my last hurdle today. Which was once I call my number from the outside and the AA picks up it would drop the call once I dial the extension. After looking at one of the cisco docs I was referring too during my sip trunk install realized I missed something. Apparently by default once a digit is dialed during the prompt the AA over a sip trunk its redirected back to the sip provider hence the dropped calls. Under voice service voip needed to remove the default and to implement no supplementary-service sip refer. Sure enough it worked!! Wanted to give thanks to guys who gave me tips.
