PortSIP UC

Wow, a soft phone that actually works! Even in the background and when screen is locked. I’ve been searching for 2 years to find something this good. Thank you for not charging high subscription costs or bogging the app down with ads. The only thing I’d like to see added is multiple SIP accounts, but that’s just nice to have. Great job.

Excellent soft phone!! One of the best I have tried yet. Also privacy oriented. Don’t change. We use both with PortSIP pbx other pbx. Having 2+ sip accounts would be helpful. Please add to the in-call screen: codec and Transport plus SRTP. G.711 TLS SRTP🔒 in the corner for example. Also it seems background noise is much clearer and picked up vs using the iOS dialer. Is there a noise cancelling on/off option for developers? Thanks!!

Why on EARTH am I required to use facetime with this now???? When I close that window it hangs up!

This app is absolutely amazing, It took me ages to find something that works so easily with my phone systems. Keep up the great work!

Allows for only one SIP account. Thar’s too toyish.

I am using this apps last 3 days it’s seams good than Zoiper.

Hi! Port sip was very good in ios12 But in new ios is very bad and has lot of crashes Please check last version and available a new version

The party in Nigeria was not hearing me, but I was hearing him during my first call today. The second is ok after two tries. It's saying server error.

Please fix this when US dialed number starts with 1. Same thing works when 1 is removed.

It works with some WiFi Networks not all, I may be a problem related to my soft-phone service provider but I’m not sure. It does not work on t-mobile cellular internet yet it works with other cellular providers internet I tried using a different sim card and I am unable to log in with my T-mobile one.
