VOIP - SIP Dialer

[Guest Priceless07]

Hi,

I am looking for a SIP/VOIP dialer for my Omnia i900 where I already have an account with actionvoip.

I have tried fring, nimbuzz but the voice quality is very bad.... i tried taukonout which gives amazing voice quality but call gets dc after 3 minutes... can someone suggest a good software to make voip calls.

Regards,

Abbas
