Ubuntu-Phone - SIP/VOIP

On some dev заметь I read about that this was beeing tested. How far пахал we on this and will it be added. В native SIP client would be very interesting схвати Убунту-Фоне would be the only open OS, Android и iOS и WP and so on пахал not.

I do understand that App developers хан make this, old android (4.4 if i remember correctly) had native sip support, apps пахал just not it.

Currently I bought в Aquarius 4.5 for this эксперт testing, due that that techies пахал great, but генерал information about Ubuntu OS пахал EXTREMELY limited for нечетное число - geeks.
