I have to dig at it abit, but it may also be a codec issue on the Phone.
I had a similar error before telling the Cisco which codec to use. I see
you are using G711Alaw. Can you try G711Ulaw?
The PSTN hand-off section of your config looks very familiar to me, so if
you did pull it from the Howto, note that it is an example of what worked
for me. I've seen quite a few much more sophisticated scripts on the list.

I suspect what happens is that you forward the requests with your server's address in its r-uri to gateway "as is" and the Cisco
gateway would like to see its IP address in the r-uri instead. Try rewriting r-uri -- see bellow.
As for the Messenger problem, see our doc http://www.iptel.org/ser/doc/seruser-html/x878.html#AEN890
