While SMS interoperability is limited to bi-lateral interworking / roaming agreements between operators, it is unlikely that full international SMS reach will be achieved by setting up more and more agreements, which are time consuming and costly to put in place.

During the same period, a few European countries collaborated in the production of systems with image coding to the H120 standard which permitted interworking at a simple level, but vendors in the United States and Japan continued with proprietary systems that were not at all compatible with any other vendor systems.

Test suites and procedures developed by the IMTC in the late 1990s demonstrated the viability of connecting gatekeepers, gateways, proxies, MCUs, endpoints and network components into integrated rich-media sessions and interoperability and interworking between IP networks and switched-circuit networks including H . 323, SIP, the iNOW!

Due to the improved electronics TXE4A and TXE4E ( or TXE4RD / IW interworking ) were able to receive downloadable updates for tariff data at bank holidays etc ., which was a major improvement on the previous Strowger, Crossbar and TXE1-4 tariff change method of manually changing switches on the exchange metering equipment.

TP-PID ( Protocol identifier ) either refers to the higher layer protocol being used, indicates interworking with a certain type of telematic device ( like fax, telex, pager, teletex, e-mail ), specifies replace type of the message or allows download of configuration parameters to the SIM card.

Interworking between TTY / TDDs and ToIP has been implemented using gateways by T-Meeting, Omnitor, Trace R & D, RNID, Center, Voiceriver, and AnnieS . "'RFC 5194 "' Framework for real-time text over IP using the Session Initiation Protocol ( SIP ) provides an overview of interworking issues.

The Interworking MSC of the SMSC, on receipt of the MAP mo-ForwardSM message, passes the SMS-PP Application Protocol Data Unit ( APDU ) containing the text message to the actual Service Centre ( SC ) of the SMSC for storing, and subsequent'forwarding'( delivery ) to the destination address and the SC returns an acknowledgement indicating success or failure.

CT2's successor, DECT, was provided with an interworking profile, GIP so that GSM networks could make use of it for microcellular access, but in practice the success of GSM within Europe, and the ability of GSM to support microcells without using alternative technologies, meant GIP was rarely used, and DECT's use in general was limited to non-GSM private networks, including use as cordless phone systems.
