[tlug] Asterisk, 2 FXOs and ISDN



I've got Asterisk@example.com (v0.6) installed in a PC with
2 FXOs (Wildcard X101P) boards, each connected to one
analog port of an ISDN TA.

when my phone rings, the TA is programmed for "global"
ringing, i.e. both analog ports ring:

    -- Starting simple switch on 'Zap/2-1'
    -- Starting simple switch on 'Zap/1-1'

problem is that both channels try to answer the call:

   -- Executing Answer("Zap/2-1", "") in new stack
   -- Executing Answer("Zap/1-1", "") in new stack

and re-direct it to the SIP extension:

    -- Executing Goto("Zap/2-1", "ext-local|2001|1") in new stack
    -- Goto (ext-local,2001,1)

    -- Executing Goto("Zap/1-1", "ext-local|2001|1") in new stack
    -- Goto (ext-local,2001,1)

one of the channels receives a pls-try-call-later:

    -- Executing Playback("Zap/1-1", "allison7/pls-try-call-later") in new stack
    -- Playing 'allison7/pls-try-call-later' (language 'jp')
    -- Executing Hangup("Zap/1-1", "") in new stack

while the other channel keeps ringing the SIP phone even after the 
caller hungs up. the channel can only be freed up by picking and hanging 
the phone up.

does anyone know if this is the expected behaviour? are there better
dialplans for "channel bank"-like configurations like this?
