Acrobit's response to G.729 's cost:
Despite the fact that G.729 patents expired, G.729 continues to be a premium codec in Acrobits Softphone and Groundwire. There was a substantial upfront cost to acquire access to G.729 licence and the patent expiration in Jan 2017 didn't make the codec free for us. If we decide to change the price in the future, we'll make a public announcement.

Any know how much better push is over TCP, in terms of battery life and reliability? Also, while zoiper on android was the best app I've used so far, it's still not as good as the stock dialler or hangouts (or zoiper on windows). Do these other two apps bring the level there esp. over data?
My VoIP.ms settings with Zoiper:
Disabled Echo cancellation
Sip
Transport= TCP, registry=300
Dialler integration, always on

what function does this have over csipsimple ?
Biggest would be
Push notification so that the app will not need to maintain a constant connection to the server and thus save battery.

Push is better because it uses the standard apple or google push notification servers. Your phone contacts these servers anyway in normal use, so there's no impact on battery life plus apple/google have already optimized the phones for their own push servers (all the stock google/apple apps use the same servers for push).

Acrobits pushes -> google/apple servers pushes -> you

TCP will always impact battery life more because it's an extra live connection the phone's radio must maintain, although you can optimize it to reduce usage. Push works with all SIP providers, where TCP doesn't (requires provider to support )

The big disadvantage for push is there's an extra 2-3 ring delay from the time your caller hears ringing to the phone actually ringing . Some impatient callers may hang up

That sounds good. How about voice quality? Anyone tried both this and zoiper and noticed a difference?

Unless a SIP app is exceedingly buggy, it has no bearing on sound quality if the same audio codec and service are being used.

Zoiper on windows 10 has been flawless for me, compared to android at least. It might be because the connection is worse on phones, or I'm not using a headset, but I do notice a difference at least.

Different hardware (and OS) is being used. It's not a valid comparison (some people also think, incorrectly, that slightly higher volumes means the sound quality is better).

All other things being equal, it doesn't matter. It's not as though server locations from the VoIP service used changes, which can be a contributing factor in latency and jitter.
It's not as though anyone should reasonably expect that using vancouver.voip.ms with the G.711u codec and VoIP.ms premium rates is going to sound different depending on the app used, with the exact
same hardware (and when jitter and pings to the server are minimal). I usually roll my eyes at anyone online who claims otherwise without that person
also suggesting an app may be buggy with certain hardware or an OS/drivers. And I see those kind of nonsense claims all over the place.
G.711u is G.711u is G.711u is G.711u.

The "push" notification travels via Google or apple push servers, then restarts the Acrobits app.

Your phone call then connects directly to your sip provider, bypassing both Acrobits push server and Google /apple push servers
so there's no difference between push and traditional udp or tcp

I forgot another big advantage of Acrobits push. Waiting for a push, the Acrobits app can be closed so it's no longer in your phone's memory. When Google/apple sends a push, your phone restarts the Acrobits app so the incoming call starts ringing. Again, the disadvantage is the longer delay your incoming caller gets while you pick up.
(Acrobits pushes to Google/ apple pushes to your phone, restarts Acrobits app, connect to your sip provider, call starts ringing)

With tcp, the sip app must stay running in your phone's memory all the time consuming resources (CPU, memory, battery, data), but it rings without much delay on an incoming call

The reviews in the Google Play are pretty bad. Is this a accurate review for it?

I thought the same. Until I saw acrobits document.

"When a device receives a push notification about a pending incoming call, it launches the softphone application. The softphone creates a special SIP user agent which communicates directly with SIPIS. Next, the softphone notifies SIPIS about its “readiness” and SIPIS then proceeds by initiating its own SIP call with the device. This new call is constructed using most of the information from the real incoming call, so from the iPhone’s point of view it just seems as if the call came directly from the calling party (while it is, in fact, just iPhone – SIPIS “tunnel”). Once this new call is established, SIPIS relays all relevant signaling information between these two separate calls."
https://doc.acrobits.net/sipis/overview ... light=push

In short, when you use push with acrobits, you answer your call by having acrobits's push server as a middle man.
there's two downsides:
1. there're security concerns. acrobits could potentially monitor your entire call. they would be able to know the whole call if they want to.
2. since you're connecting to acrobit's sip server instead of your provider's sip server, it would create extra latency most of the time.

I'm really thinking of making a sip softphone myself.......
