Skype

Aah for SIp to work shouldnt all ports be open? I only have port 9201 (WAP) open on my data network. Can you route this trough that?

Yes, for registering to standard SIP proxy such as iptel.org, you would need port 5060 for signaling and another for media opened up in your firewall. But if you can have your own proxy somewhere in the Internet which in turn talks to std proxies, then you can use any port you desire. But then you will have to port your own SIP UA (client) to phone so that it uses non standard port - the inbuilt SIP UA might not allow ports to be changed - someone (silvio?) already having SIP UA enabled on phone can confirm this!

But this is definetly a better option than porting skype (proprietary) or GnomeMeeting (H.323 obsolete?). One catch though - the SIP UA on phone has only amr codecs supported which are usually not available on other freely available SIP UAs for desktops - but it should be easy to add this codec in kphone or sipset. Or instead port kphone/sipset/minisip to phone with other codecs.

Not sure what all codecs minisip supports. But should be easy to add the h.264(amr) codec just released by Nokia:

i just found minisip for linux pda, but its not skype compatible.

skype uses proprietary p2p protocol, not SIP.

i know...
maybe its better to go with sip than with skype's propritary codec.

maybe we could program a plugin for skype to get the audio signals(mic and speaker) from skype to the sip app....



http://gizmoproject.com -> same like skype but with open standard SIP..

Im really interested in the Gizmo project. Unifortunately they only have a Debian and Linspire version.

Debian ok, but why in hell Linspire????????

@heamnrulez
They have a skype for pocket pcs that use same processor, but with minium of 400mhz(about 80 MIPS raw more of processor power than e680 processor)... and pocket windoze have some optimizations already done in the multimidia side(at least on armv5 instructions I think, wmmx is not used since it is pxa27x only).

@rhizod
Yes, they can reduce quality to dropoff processor need, maybe they already do something like in the ppc version...


Intel have the IPP library(not sure about licensing things...) that has lots o wmmx stuff, it can help porting of heavy audio codecs if someone wanna use them.
