Summary:                    On Mac OS X PowerPC, Asterisk 1.6.0.1 cannot create
outbound channels
Description: 
Although incoming SIP and IAX2 channels work, all attempts to use the Dial
command to create SIP, IAX2, or Local channels fail as follows:

    -- Executing [953 at localsjphone:1] Dial("SIP/localsjphone-0183ca00",
"IAX2/mainpbx/953,120") in new stack

lock channel list

or

even local:

This problem persists in 1.6.0.3.

I'm including a patch which does the "hack" russell used above, but it
seems like the real cause for failing to lock should be found.
