I like how easy it was for me as an agent, or even customer myself when using this software with my computer at home! It's very user friendly so anyone can use them easily without any problems from beginning till end if you know what your doing (which i think everyone should).
Nothing really but just make sure u have enough knowledge about computers because there are some things which might be confusing sometimes especially those who dont understand much abt pc stuffs etc., But overall its good product!! If ur looking into softphone products then definitely try out Tp smart dialers they're great. The best part being able too call landlines through Sip Trunking feature also makes calls more reliable than other competitors out here now days..
