  Subject: [cisco-voip] ISDN Incoming Calls Rejected


  I've got a weird issue where incoming calls from ISDN-PRI are rejected after about 3 incoming calls: 

  The IOS box is rejecting the ISDN side with:

  Cause i = 0x80AF - Resource unavailable, unspecified



  No SIP messages are generated, and all of the DSP debugs look ok... The box has plenty of DSPs, it's only after 3 simul inbound calls... All outbound works fine... Has anybody seen this before? 

  Is there a way to busy-out single B-Channels?
