We have a cisco based environment where a “Call-Info:” call header is being included and causing HMP to generate a SIP Parse error instead of handling the call. In the same environment a secondary set of SIP (checked side by side)without the Call-Info: header works fine but the addition is required by other items/applications present in this alternative environment. What could be the cause as the header format looks ok to me?
