libss7 is a userspace library for providing SS7 protocol services to applications. It has a working MTP2, MTP3, and ISUP for ITU and ANSI style SS7, but was written in a manner that will easily allow support for additional national specific variants in the future. For a working reference implementation, see the various link test programs, as well as the Asterisk Open Source PBX.
DialFOX is an express dialplan report generator that is used with the Asterisk PBX system. It is able to make an inventory of any device (such as SIP phones, softphones, and ATA) that is active in a local network. It lists their extensions, IP address, username, caller queue, device info, and comments. It can easily access any SIP device that is found in the LAN. Furthermore, DialFOX provides additional information about phone devices like firmware release, key functions, and more.
