I have an odd problem between a Nortel BCM and Asterisk (1.2.4) Zaptel (1.2.3).<br><br>Calls all appear to be working fine, however, when someone originates a call from the PBX and the Switch returns a 486 (Busy) the PRI channel hangs in a busy state indefinitely. Subsequent to this, the PBX side shows the channels as IDLE and apparently attempts to route calls to the siezed/BUSY channels.
<br><br>Normal calls (those that are successful and subsequently hungup) appear to function normally. It's only when the number is BUSY that a hangup is not detected on the PRI.<br><br>Any suggestions would be greatly appreciated.
