asterisk users - Mar 2015 - Problems playing audio file over a Page

All;

    I have a problem that I?ve been working on for a while now, but I?m
stuck and can?t see what the solution is. I have an Asterisk 1.11 server on
a public IP address and have two phones registered from behind a NAT. I can
send a page to/from each phone without a problem. My problem is that if I
play an audio file over a page, the page disconnects after a few seconds (
seven seconds to be exact ). 

I?m playing the audio file like so: 

exten => s,n,Page(${AVAILCHANS},A(demo-congrats,q) 

 

In the CLI I?m seeing this:

[2015-03-27 11:40:26.360] Got  RTP packet from    X.X.X.X:2256 (type 00, seq
021523, ts 1374867997, len 000160)

[2015-03-27 11:40:26.362] Sent RTP packet to      X.X.X.X:2256 (type 00, seq
050875, ts 050560, len 000160)

[2015-03-27 11:40:26.363] WARNING[11325][C-0000002d]: pbx.c:6709
__ast_pbx_run: Timeout, but no rule 't' or 'e' in context
'scheduledpages'

 

Where X.X.X.X is the outside IP address where the phones are coming from.
I?m seeing the Got?Sent messages several hundred times while the audio is
playing. Like I said, simply paging an extension with a human voice works
just fine. Any insight at all would be greatly appreciated.

Thanks much;

John
