Abstract

See full text

Described herein are techniques, devices, and systems for handling Session Initiation Protocol (SIP) messages with malformed header fields. A communication device that receives a SIP message from an additional communication device may identify one or more identified header fields of a plurality of first header fields in a message header of the SIP message that correspond to (e.g., match) one or more second header fields in a list of second header fields accessible to the communication device. If the communication device determines that the one or more identified header fields are not malformed, the communication device may process the SIP message without regard to remaining header fields in the message header. If, however, the communication device determines that at least one identified header field of the one or more identified header fields is malformed, the communication device may reject the SIP message.
