Nope, "tcpdump 'udp port 5060'".

While that's a useful data point, it's not relevant to the problem.  A
significant portion of the SIP stack was re-implemented in 1.8, and Polycom
phones are on the desktops of nearly every Asterisk developer.  Since you
aren't using a Polycom, the SIP stack on that device is implemented
differently, causing possible incompatibilities.  This is why the tcpdump
will be helpful:  to figure out what is different and why it doesn't work.
