hi,
this is just from the top of my head . I am working with pjsip on symbian
and studying for implementing a voip tunnel for it.
If I implement a tunnel ( using the word "tunnel" is an exaggeration , I
am simply encrypting the packets before they go out of the software and
decrypting them at the destination before sending it to the server ) , will
it work in places where VOIP is blocked ? (like UAE)
The idea is like this:
pjsip software <---------------------------------> A proxy server
<-----------------------------> SIP Server
Encrypted packet
Decrypted packet
I am not thinking of anything sophisticated , I shall pick the simplest
encryption with a static shared key and use it to encrypt the packets just
before they go out of the software ( i think the file to modify is pjlib /
src / pj / sock_symbian.cpp ) and on the receiving end decrypt them at a
proxy server and send it to the sip server .
Again , this is not something that has been thought through . Just came to
my mind and I am putting it out there for discussion . So can anyone comment
on this ?
