We have created a new IVR server with a new SIP provider. During testing have we found out outgoing calls are all resulted in "Disconnected" state, while incoming calls are successful.
We have set up a technical session with the SIP provider, but before having a meeting with them, I wanted to hear from the expert.
Please see the attached logs: the Wireshark shows "401 Unauthorized" but not really sure if this was the cause because that displays even during "waiting for call" state.
Your help is much appreciated in advance.
