[SIPForum-discussion] Clarification needed Pls - IP problem

[sipsipsip sip]

Hi All,
      What could be the problem !!??

      Iam using a IMS client , where Registration is done thro OTA . The
problem while registering with the phone while using Airtel SIM is that ,
the client is able to register only with certain IP's ( Ex:117.124.12.32)
but not able to register with certain IP's such as (Ex:117.124.122.132,
117.124.143.144 ) . what would be the problem ?? . Both the IP's have the
same subnet mask . IP is got dynamically from Airtel by doing  a dial up .

Setup is like -- Mobile is connected to the system , make a dial up
connection by using a modem . Mobile has the Airtel Sim and an IP is  got
from the Airtel Network .IP got is configured on the mobile as well as in
the server.  Hope you understand the setup :)

Regards,
vinod
