". . . 所有VOIP电话不能回避的一点就是依赖互联网的连接质量. . . ", yes but + "technical" ~= router or whatever else. I have friends who used Vonage for years with no problem while another friend who has problems for 3+ months.
Even Vonage cannot figure out the problem yet. The symptoms = line sounds busy for dialer while his phone just rang once, other times he hear the caller, not vice versa. It was all OK 6 months prior. (<- this is information to share, not looking for soluction. We've worked with computer hardware + software for > 30 years) |
