I have downloaded Express Talk 1.01 for Pocket PC.
I am using this for a SIP account.
It works fine with my Desk Top but with my pocket PC I get a notice under networking option, which says "this device is blocking port 8000. I tried and changed the port to 8002 or 8004 but nothing happened.
I can hear the sound from other end but my voice can not be heard by other party.
Any body has a clue what I have to do to rectify this and the port 8000 can be unblocked. If this is due to a Fire wall how can I find fire wall in my pocket PC which is HP IPAQ RW6815.
