Objective Systems is a software products company specializing in standardized data communications protocols. We have experience with XML and ASN.1-based protocols. Types of projects we have done in the past include the following: - Development of encoders and decoders for binary message formats used in 3GPP and LTE technical specifications. These are normally specified using ASN.1, CSN.1 or tabular notation.- Telephony call detail record (CDR) processing involving the conversion of BER-encoded CDR files in formats such as Ericsson R10 or TAP3 into XML or CSV format for insertion into a database. - TAPI / CSTA client/server telephony applications involving PBX device control. - H.323 signaling and call control for the Asterisk open source PBX. We are experienced in C/C++, Java, and C# programming languages on Windows, Linux, UNIX, and Mac OSX platforms. We also have experience with embedded development included Symbian, Microsoft Win CE, and J2ME.
