I'm going to take your word for it, I know my way around C++ but I'm not a programmer myself. However, after reading the ietf sip draft I can write a UAC or a UAS in perl in a matter of days, but writing anything for h.323 from scratch would take me forever. When the services get as complexe as RTC you may want to have a simple protocol that can be coded easily by many in order to make it grow. > Classic case in point of why doing RTC in H.323 is easier than SIP.

It takes a great mind to build great things. I refuse to think that, if you'd concentrate your effort on sip nat traversal you wouldn't do it. However, I didn't have big problems with SIP under NAT so far. > BTW: If someone has a cool GUI idea for PacPhone and is not overly complex > and is not going to be a huge amount of rejigging, I am very interested. :) I would suggest a skype-like GUI, or, if you used MS Office Communicator I would say it has the best GUI from what I've used. If GnuGK takes this road, even if I'm a fan of h.323 in favour of SIP, I would say it needs to go multiprotocol and do some SIP stuff as well. There is a very simple reason for that - mobile phones. The most popular mobile phones have a sip client now. I have one myself and it works perfectly over wifi (under nat). A "follow me" service should work with both protocols ?? This is the market trend in mobile phones, you can't change it and even if you'd make pacphone to work under windows mobile or symbian os, it still wouldn't be intergrated with the phone like the sip client is and many people won't be able to install it anyway. I would love to see the day when I would do RTC with PacPhone and gnugk and use a follow-me service with a sip client !
