[asterisk-users] DAHDI/1-2 v. DAHDI/2-1 ??

[sean darcy]

I've got a single TDM 400P board with two internal ports and 1 external.

chan_dahdi.conf:

context=internal      ; Uses the [internal] context in extensions.conf
signalling=fxo_ks     ; fxo_ks not auto  Use FXO signalling for FXS
group=0
channel => 1          ; Telephone attached to port 1
channel => 2          ; Telephone attached to port 2

context=incoming-pstn-line  ; Incoming calls go to [incoming-pstn-line]
signalling=fxs_ks     ; fxs_ks not auto Use FXS signalling for FXO
faxdetect=incoming
busydetect=yes
group=1
channel => 4

But look at what happens when the first internal line and the external 
line is busy and a sip call comes in:

     -- Executing [s at incoming:3] Dial("SIP/sip-0000000d", "DAHDI/g0,60") 
in new stack
     -- Called g0
     -- DAHDI/1-2 is ringing

If the first line is free, everything works:

     -- Executing [s at incoming:3] Dial("SIP/sip-0000000e", "DAHDI/g0,60") 
in new stack
     -- Called g0
     -- DAHDI/1-1 is ringing

The second internal does NOT ring, because it is DAHDI/2-1:

     -- Starting simple switch on 'DAHDI/2-1'
     -- Hungup 'DAHDI/2-1'

when I go off-hook on the second line. And the external line is DAHDI/4-1.


Is this a bug, or am I missing something really obvious?
