1. A communications method, comprising:
enabling message blocking at a first Session Border Controller (SBC) for Session Initiation Protocol (SIP) messages including a first key value in response to a first threshold number of SIP messages including the first key value having caused a SIP message processing failure;
receiving, at the first SBC, a first SIP message including at least one key value;
determining, at the first SBC, if message blocking is enabled for one or more key values included in the first SIP message; and
performing, at the first SBC, one of:
i) dropping the first SIP message in response to determining that message blocking is enabled for one or more key values included in the first SIP message; and
ii) processing the first SIP message in response to determining that message blocking is not enabled for a key value included in the first SIP message.
