[Serusers] ser on wireless interface

[Annie Sasidar]

Hi,
 I am using ser as a registrar/proxy server. I seem to be able to register
a client on the wireless interface on the sip server only if the name of
the client is included in the hosts file on the server that too the ip has
to be static. Is there a way that i can have mobile wireless client
register with dynamic ip on ser? Any insight would be of great help.Does
ser listen to wireless clients on any particular port no. other than
default 5060.
Please guide. I am not able to pass voice packets between a wireless and
wired client that are registered on the ser.  I am stuck. Any hint would be
of great help.

Thanks,
Annie
