When using cloud-based SIP providers, the “in-band audio call progress” feature MUST be enabled.

Viking IP Programming -- “Phone settings” tab

Viking Device Manager – “Speaker Settings” section

Also, If using VOIP.MS, “Caller ID” is REQUIRED.

(On the VOIP.MS portal, go to “Main Menu”, “Account Settings” and then click on the “General” tab. Enter a phone number in the “CallerID Number” field and apply the change.)
