Anyone have any recommendations for 3rd party SIP clients for Android/iOS to use with OfficeServ?
I've been testing with Zoiper and think it works pretty good, even the free version.
I've seen Bria mentioned frequently, but I don't like the monthly payments..

Would love to hear some feedback and reviews of other applications that others use.

Bria was great when it was a once off charge.
For android you can use wevoip which works very well.
It's crap on ios (os7000 version, the scm version worked)
I've used zoiper, had issues on ios but I think that may have been me not setting it correctly

"Grandstream Wave Lite - Video" works great for me.

I use Wave-lite too. Nice and easy. You can set up multiple accounts making it easy to switch from an internal address to an external.

We try to use WeVoip if possible, but it is problematic on newer Samsung devices (on S20 it would not connect to server, but after a few weeks it somehow magically connected..)

Haven't used Wave-Lite before, will try it out.
FoneJacker, Bushmills - did you use this app on iOS and had good experiences?

Seemed to work pretty well on ios too.
