[Asterisk-Users] New 'n' priority

[Bill Seddon]

Can anyone point me to documentation covering the new 'n' priority.  I've
downloaded and have working v1-0-2.  But when I attempt to use the n
priority - for example:

exten => s,1(checkavail),ChanIsAvail(${EMERGENCY_TRUNK}) 
exten => s,n(dial),Dial(SIP/1001)

Asterisk generates errors containing the text "pbx_load_module: Invalid
priority".

Can anyone help or show me what I'm doing wrong?
