SFLphone is a robust standards-compliant enterprise software phone, for desktop and embedded systems. It is designed to handle several hundreds of calls a day. It supports both SIP and IAX2 protocols.
SpanDSP is a library of DSP functions for telephony, in the 8000 sample per second world of E1s, T1s, and higher order PCM channels. It contains low level functions, such as basic filters. It also contains higher level functions, such as cadenced supervisory tone detection, and a complete software FAX machine. The software has been designed to avoid intellectual property issues, using mature techniques where all relevant patents have expired. See the file DueDiligence for important information about these intellectual property issues.
VoipMonitor gui/dashboard
VoIPmonitor sniffer implements SIP, Cisco SKINNY, RTP, RTCP and UDPTL VoIP protocols analyzing quality of calls - packet delay variation and packet loss according to ITU-T G.107 E-model which predicts quality on MOS scale. It is written in C++ and designed to handle thousands of simultaneous calls. Each call can be optionally saved to pcap file format with either only Signalization SIP/SKINNY or including also RTP, RTCP and UDPTL protocols. VoIPmonitor can also decode sound and play it over the commercial WEB GUI or save it to disk as WAV. Supported codecs are G.711 alaw/ulaw and commercial plugins supports G.729a/G.723/G.722/iLBC/Speex/GSM/Isac/Silk. VoIPmonitor uses jitterbuffer simulator to keep both direction of call synchronized.
