Which modem protocol includes the ability for a modem to generate DTMF tones during a voice call? Is that part of one of these?:<br />
<br />
Modem Protocols: ITU-T V.92/K56Flex, ITU-T V.34bis, V.34, V.32bis, V.32, V.22bis, V.22, V.21, V.23 Bell 212A/103, V.80<br />
<br />
I need to make sure that the modem I specify for an application has the ability to generate (as directed by the appropriate AT commands) DTMF tones during a voice call.<br />

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.
