Abstract
A node in a converged network converts a session initiation protocol (SIP) message to a signaling system 7 (SS7) message. A SIP INVITE request is received by the node and the node determines whether the SIP INVITE request is destined for an SS7 user. If the INVITE request is destined for an SS7 user, the node determines whether the INVITE request contains MIME-encoded text and constructs a short message service (SMS) message containing the MIME-encoded text. The SMS message is routed to the SS7 user. In addition, the node constructs an initial address message (IAM) and routes the IAM to the SS7 user.
