[Serusers] mobile client registration

[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.

Thanks,
Annie
