Any advice for VOIP app to make use of with SIP:// or customized URI to name from one other app?
I attempted Linphone ( bug with outbound calling) and Groundwire ( not free, requires registration, unsure about MDM & bulk deployment compatibility ).
The Options I care about are
- IOS 15 compatibility
- RELIABLY make outbound calls utilizing URI from browser or different app
Good to have:
- no registration, can use full ://quantity@ipaddress to name with out a sip account setup
- return to browser or different app on name finish
- config scheme xml or different MDM compatibility/options inbuilt
- free, low value
