Possibly a dumb question, but can I verify that an ATA or IP Phone is operating correctly by registering it to the SIP Server here (»www.iptel.org/service/
) and dialing some of the test numbers they provide?
Or, is there a better way? I know that there is SIP Server software which can be installed on a PC, but I prefer to avoid that hassle- a Public server is preferred. A free solution is best.
