SIP VOIP

[har]

The SIP VOIP built into higher-end Nokia phones seems promising. Integration into the address book means seamless dialling and receiving of VOIP calls via wifi or 3G. I tried out a free (antisip) SIP number and I found that it works on 3G (not EDGE) and on my ADSL. But it doesn't work on a friend's ADSL (though Skype, for instance, does). Why is that? Is Telkom-ADSL blocking SIP??? Or is it just a router setting?

Sounds like it's a setting on your friend's router.

Sounds like a router setting or proxy issue.

I have successfully tested SIP using PortGo softphone (free version) on a Samsung i780 smartphone which runs on WIndows Mobile Pro 6.0

Remember with SIP softphones, only the licensed/Pro versions support the better codecs and thus provide better voice quality and more stable connections.

You can also try fring or nimbus. Both of them works excellent on both 3G and wifi.
