This R2.9 revision of the CLID detector provides the TYPE 1 (on-hook, between first and second ring, or
before first ring) signal detection and returns the message raw byte data without parsing of particular fields
such as message Type, Parameter(s) Type(s), etc. The decoding of the message meaning should be performed by the user application.主叫號(hào)碼識(shí)別CID算法for TI DSP
PTypes (C++ Portable Types Library) is a simple alternative to the STL that includes multithreading and networking. It defines dynamic strings, variants, character sets, lists and other basic data types along with threads, synchronization objects, IP sockets and named pipes. PTypes also offers message queues as an alternative method of thread synchronization. Its main `target audience is developers of complex network daemons, robots or non-visual client/server applications of any kind

Siproxd is a proxy/masquerading daemon for the SIP protocol.
It handles registrations of SIP clients on a private IP network
and performs rewriting of the SIP message bodies to make SIP
connections work via an masquerading firewall (NAT).
It allows SIP software clients (like kphone, linphone) or SIP
hardware clients (Voice over IP phones which are SIP-compatible,
such as those from Cisco, Grandstream or Snom) to work behind
an IP masquerading firewall or NAT router
