asterisk users - Jan 2006 - Page() and Asterisk 1.2.3 Problems?

Has anyone else had problems with the Page() application not working 
under Asterisk 1.2.3?
We use Cisco 7960 phones and set one of the lines to auto answer. When 
someone dials the paging extension it calls the page app and invites all 
the lines on the phones that are set to auto answer into a meetme 
conference where all the members are muted except the original caller.

When I try to use the same dialplan logic that I used in Asterisk 1.2.1 
for paging under Asterisk 1.2.3 it doesn't work. Basically the 
auto-answer lines get called but no one can hear anything. Then within a 
minute or two the asterisk console spits out these messages:

Jan 27 15:09:13 WARNING[5429] app_meetme.c: Unable to write frame to 
channel: Resource temporarily unavailable
Jan 27 15:12:11 WARNING[6228] app_meetme.c: Unable to write frame to 
channel: Inappropriate ioctl for device

Jan 27 15:21:32 DEBUG[6502] app_meetme.c: Ooh, something swapped out 
under us, starting over

The first line a of output above is spammed over and over. The second 
and third show up as well but not as much.

Here is some snippents from extensions.conf

Like I said before this was working with 1.2.1 but 1.2.3 doesn't seem to 
like it. Any help / suggestions would be appreciated if you see a coding 
error.
