asterisk users - Jan 2008 - WARNING[31046]: chan_sip.c:4978 process_sdp: Unable to lookup host in c= line, 'IN IP4 100101'

Anyone else have issues with T.38 where the call drops after T.38 is
attempted to be negotiated, with a message like the below?

 WARNING[31046]: chan_sip.c:4978 process_sdp: Unable to lookup host in
c= line, 'IN IP4 100101'

What are the values for type for chan_mobile?

headset and phone ???

I get my Treo650 to pair.

hcitool scan shows the device.
hcitool con comes up empty.

I go into Asterisk cli.

mobile search shows the device (while I am waiting for a response, I see 
the phone showing a connection being set up).  And I am shown that I 
have a device that is:

NOT available and is a headset

OOPS.

So I think I need to force Asterisk to see this as a phone?  Or is there 
something I need in a bluetooth config file?

The problem is that 100101 is neither a valid IPv4 address nor a fully-qualified
domain name.
