The default SIP Options message header on AudioCodes equipment is using the SBC’s SIP interface IP address in both the To and From header field when sending keep-alive Options, which has been messing with my OCD over the years, but never really caused any issues. When looking at traces in “The Monkey” it is difficult … Continue reading Manipulate SIP Options Header on AudioCodes SBC
