Picked up an Obi110 this week in hopes of leaving Vonage for some other VoIP as I'm a low minute user and can likely save $20/mo or more. The exercise has been fairly interesting, though a little frustrating and time consuming as well as the Obi doesn't really have a whole lot of concise technical information if you need to do anything that the really basic setup.
Anyway, onto my problem.
* Obi110 is setup with a static IP, and configured into the router QoS with the highest priority and placed one rung higher than the Vonage adapter that's been working without issue for years.
* Initial setup was with Google Voice on SIP1. Has worked awesome for the little time I've been testing it.
* I then setup a Callcentric account for e911. That process was extremely simple, I tested it and 911 reported the correct address. So far so good.
* I then started researching exactly how I would port my existing number, and if I really wanted to go through the effort and expense of giving it to Google Voice with the knowledge that in a few months who-knows-what-will-happen.
* So I decided to get a full inbound/outbound payg account with Callcentric to test with as I'd be happy paying $5/mo for more robust and long term service without having to wonder what will happen at the end of the year.
* Currently Callcentric is on SIP1 and Google Voice on SIP2, using GV purely for testing comparison at this point.
My issues is that on my end, and on the other persons end, the call quality through Callcentric is worse than with Google Voice. The physical call quality is lower with a generally less-clear and mildly distorted sound, there's some occasional breakup and a seemingly higher noise floor. It's not unusable, it's just not as clear. Dial using the same phone, same everything, but through Google Voice and it's instantly and noticeably better sounding.
I've adjusted the codecs so that ONLY 711U and 711A are enabled, in that order for Callcentric. Google Voice on SIP2 has the default Obi110 codec profile which has that same two codecs prioritized, but with others below that still enabled.
I ran a couple test calls, finally noticed the current call status where I can see quality measurements and which codecs are being used, and that you can actually record the codec used. During my test calls both Callcentric and GV used the same 711U codec. See attached for the two call quality reports. Not comfortable sharing the conversations my wife and I had to test the calls, but maybe there's some test tones I can play with an iPod held up to the phone that I can record and share? There must be some tone that's difficult to compress and transmit well via VoIP to stress test it.
What I haven't tried is a wired phone into the Obi110 instead of my AT&T DECT 6.0 in case that has some bearing. I also haven't tried swapping Google Voice into SIP1 again and putting Callcentric onto SIP2, though I doubt that will have any bearing as that's the way it was originally and GV sounded great on SIP1.
Any thoughts on this issue? All I've read is how great Callcentric's quality is.
Likely unrelated I had my Obi110 automatically power cycle itself for no apparent reason while on an active call. I was talking, I heard an audible background noise, the noise quickly ramped up in volume, then I heard the Obi110 power cycle. The call was not logged to history. I believe I was using Callcentric. I called the person back on Google Voice without issue.
