I have an IAX-Account from german voip-operator Portunity and I use zoiper free as softphone.
Since some weeks before the connection after some hours get broken. Restarting Zoiper helped sometimes, but I can't control zoiper every minute, obvously and I need to get the calls.
With Yate this problem does not exist, so I think, it could be a special zoiper problem. Can you help me, please?
No I use SIP for connecting, but phoning quality is much better with IAX.
