I don't use such an IP Phone. So, I wouldn't know the answer to your question. However, if you wanna save $$$$ and also would like to be able to have many different SIP and/or other protocols lines with an existing ATA devices, your best solution is to use a Digital PBX System, i.e. Asterisk
, etc. If you had an old computer desktop and don't mind wasting electrical bill, you sure can use it as your PBX System. For me, I would prefer to shell out no more than US$20 to invest on an inexpensive Linux embedded system and use it to run any PBX System. As of this writing, I am using a Seagate DockStar running on an OpenWRT
OS with FreeSWITCH
as my PBX System. It draws a little less than 3 Watts of electricity and provides many different SIP lines, Google Voice services, and among other things with two extensions.--
don't and stop are the ONLY two 4-letter words considered offensive to men, but not when used together.
