Had another interesting issue today. My wife (why does it always happen with her??) tried to leave a message on the VoIP phone and it cut her off after about three seconds. I have not been able to reproduce this.
I figured out this issue. My wife has a very soft voice, and the voicemail server's silence detection is overly sensitive, so it was not aware that she was still speaking
I'm not yet sure if that's adjustable.
Are any of you guys using voip.ms during periods of high internet traffic?
As PhotoJim mentioned, QoS is typically your issue to solve, not the voice provider's. I have heard excellent things about WRT54GL routers with Tomato firmware. I personally do not use QoS on my network at the moment. Since I'm the only heavy user of the Internet, it is not a problem for me to shut down any large uploads when I want to use the phone.
1) Does the voip.ms "premium" rate guarantee that you're on the G.711 codec @ 64kbps?
No, call routing is something different from codecs. You need to specify the codec you would like to use in the configuration of your SIP device. If memory is correct, in the PAP2T, the setting is called "Preferred Codec". You may also need to turn on "Use Preferred Codec Only" to force G.711 at all times.
3) Does voip.ms provide automated monthly (credit-card) billing?
It's pay-as-you-go, so you deposit a sum of money into your account (minimum $25) and it uses it until it's gone. You can have the system send you an email when your account gets low.
5) This looks like a pure voip play, so I'm assuming that above and beyond caller ID, there are no telephony features like call-waiting or voice mail. Is that correct and if so, what do you do for voice-mail?
This question was already answered before I got to it. However, I thought I'd chime in and say that one nifty thing about VoIP.ms that my previous provider didn't support was the creation of SIP URIs that point to a voicemail account. "I'm sorry, Bob is not in the office. Would you like his voicemail?"
