A call will not connect

Things worth checking, in order:

• The other person must have opened the app at least once on their phone.
• Microphone permission must be granted, in the iPhone's Settings under Fariin.
• Notifications must be allowed on their phone, or their phone cannot be woken to ring.
• A very restricted network, such as some office or school wifi, can block the connection a call needs. Trying on mobile data tells you quickly whether that is it.

If it still fails, contact us and say roughly when you tried and where both of you were.
