Hi,
What did you assign the Service number to? A Call Queue or a Auto Attendant?
If it is a CQ you might here a ring back tone first, not sure if MS sends a 180 Ringing with SDP or without (with or with out ring back tone media). And shortly after that you should here the Welcome message or directly the On Hold music.
If it is a AA you should here the Welcome message and then the IVR menu.
