credentials. Enable this option only if you are sure that the
service provider allows it, e.g. an IP PBX may allow it.

device will bridge the call instead when performing a call
transfer (which consume some resources on the device) No

public address) in Refer-To header of SIP REFER. If disabled,
the target's Contact will be used instead Yes
