[Asterisk-Users] No Ringback on Iconnect

[Kevin]

When I place a call using Iconnecthere or Nikotel as my sip provider, I hear no call progress such as ringback when making a call.  If I program the SIP phone to directly access iconnect or nikotel I do hear ringing when the outbound call is placed.  Does anyone else have this problem or offer any suggestions?  Thanks, Kevin
