What is a User Agent (UA)?
A user agent is the software or hardware that you use for calling.

Software user agents (or softphones), such as the Counterpath X-Lite softphone, allow you to place and receive calls using your computer, a microphone and headphones. There are also other software user agents which function like IP PBX systems, such as Asterisk, 3CX, pbxnsip...etc. Any SIP/2.0 compatible software is an example of a software user agent.

Hardware user agents are equipment that connect to your broadband internet connection (such as DSL or Cable) and let you place and receive calls using a traditional telephone. Hardware user agents may be IP phones, hardware PBX systems or pretty much any SIP/2.0 compatible hardware..

Please visit our support page for a list of devices (UA) that we have tested with our services, as well as the individual setup guides for those UA.
