Telephony software is software referring to telephone services into computer networks. Some examples of IP telephony software include five9, bsc-it, and cisco.
Voip is a telecommunication network that uses internet networks and IP telephony instead of traditional telephone networks.

Internet telephony is also called IP telephony. The signal is transmitted in "data packets" through same cables as Internet connection established. Voip is a new form of data transmission technology. It uses IP networks for transportation of voice from one place to another. There are many names for this type of phones. Voip phone, internet phone, broadband phone etc. all are used for the same technology.
expand their commercial and mercantile network
I suppose you are questioning about major cellular/telephony and data networks. These networks are usually connected to their backbone by terrestrial connections mostly. In case of natural disasters, these connections got damaged. As a result, the network got disrupted.

3G is the third generation of tele standards and technology for mobile networking, superseding 2.5G. It is based on the International Telecommunication Union (ITU) family of standards under the IMT-2000.[1] 3G networks enable network operators to offer users a wider range of more advanced services while achieving greater network capacity through improved spectral efficiency. Services include wide-area wireless voice telephony, video calls, and broadband wireless data, all in a mobile environment. Additional features also include HSPA data transmission capabilities able to deliver speeds up to 14.4 Mbit/s on the downlink and 5.8 Mbit/s on the uplink. Unlike IEEE 802.11 networks, which are commonly called Wi-Fi or WLAN networks, 3G networks are wide-area cellular telephone networks that evolved to incorporate high-speed internet access and video telephony. IEEE 802.11 networks are short range, high-bandwidth networks primarily developed for data.
A Category 5 (Cat 5) cable is used for carrying signals. It is a twisted pair of cables used for computer networks such as Ethernet. It can also be used to carry telephony and video signals.
VOIP stands for Voice Over Internet Protocol. VoIP or voice over IP is a unique type of communication technology. As the name suggests voice is transmitted through IP networks such as internet or packet switched networks. Voip has many other names also like IP telephony, broadband phone, internet phone etc.
