Re: [Asterisk-Users] Musical interruptions

You know, I've seen something that may be related. We occasionally get 
DTMF inserted into the middle of a call, when no party on either end has 
pushed any buttons. I suspect something goes wrong and some data packet 
is mistakenly believed to contain out-of-band DMTF signalling and the * 
box is faithfully inserting it into the stream. But this is just a total 
guess. Perhaps you're seeing another manifistation of the same issue.

Whilst on a call, I'm getting the following...

   -- Started music on hold, class 'default', on SIP/phone3-a7d5
   -- Playing 'pbx-transfer' (language 'en')
   -- Unable to find extension '#' in context 'default'
   -- Playing 'pbx-invalid' (language 'en')
ie - without anyone pushing keys - I hear the music on Hold - as does
the calling party.
Are we somehow managing to sound like the tone for a '#' ????
My BT100 phone is set up for DTMF=info
This appears to happens quite randomly.  Suggestions?

I'm also getting quite a few...

.. but am putting that down to running this extension (SIP Phone) over
multiple 802.11 segments - in a semi-hostile environment. (I'm not the
only person using 802.11 - there may be channel clashes)
