Abstract
In some implementations, a device may receive a session initiation protocol (SIP) message. The device may determine that the SIP message does not include a parameter indicating that a first portion of the SIP message is to be processed as a telephone number. The device may perform one or more actions including one or more of: determining whether a second portion of the SIP message includes information identifying a service; determining whether the first portion of the SIP message includes a code; determining whether the first portion of the SIP message is formatted according to a format associated with a telephone number; or determining whether the first portion of the SIP message includes characters that are different than hexadecimal characters. The device may selectively cause the SIP message to be routed using the first portion of the SIP message or routed using the second portion of the SIP message.
