Quote from the review:
“Overall, the SIP Phone product is a very innovative products. I had personally test on it with another IP Phone is at another locations. The voice quality was very good and clear just like the normal house phone.
But, the setup for this SIP Phone is not a easy job. Fortunately, Ovislink had send me the setup guide for the easy of install and setup. However, the MSRP of each Ovislink SIP Phone is at $120 USD. Remember, you will need atleast two units of the SIP Phone in order for the live conversation. For a long term usage, the IP Phone will save a lot for your phone bills.”
