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 ? -- Regards Shrouk Khan (Khan) System Administrator / Telecommunication System Developer Office: +354 4400807 (Reykjavik) +44 2031370800 (London) Mobile: +66 875049439 (Bangkok) Web: www.softverk.is Reykjavik, Iceland // London, UK // Bangkok, Thailand

hi, actually going through the source code , i came across pjlib / src / pj / ssl_sock_symbian.cpp . Is this class used for both sip and voice transmission over the network ? So , what happens when I have a ssl capable proxy / sip server on the other end ? will the ISP be able to detect the traffic type ?
