[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?
