Vestalink Call Quality
BigJim_McD:
It would be greatly appreciated if there were a way to pick the preferred Audio Codec on the Vestalink Account Settings page. I suggest a short note or hint of the Pros and Cons between picking G729 and G711 along with a check box to select either G729 or G711 as the preferred Audio Codec.
For now, the more experienced users that manage their Obi devices on OBiTALK can use the "Expert Configuration" Tool to disable G729. Also those that manage their Obi devices manually via direct web access can disable G729 to insure the use of G711. Those that have lower band width should stick with G729.

This codec information seems so valuable. I'm really glad I stumbled onto this discussion. It might be valuable to a bunch of us using OBi's. It's little tweaks like this one that can make a big difference in call quality and satisfaction. I'm in the process of going through the headache of re-purposing some high-end interconnects in my surround system that I know will only be a small tweak, but that's what it's all about. Otherwise, just any ole gear will do.

Hi Everyone:
I appreciate the feedback. I believe we have solved the issues with the 404 calling problems. But I will need more feedback. We have not had any support requests regarding these problems for a while. Furthermore We do not block any calls to the lower 48 states regardless of high cost etc. All other numbers can be reached by dialing 011+the number.
As far as Google voice latency, we are using a different carrier than Google Voice so the calls from Google Voice go over the PSTN before they get to your Vestalink account. The best way to solve this latency would be to port your number to Vestalink.
I would like some more feedback regarding the g711 vs g729 codec. The g729 codec is what we use standard on our ht701 devices because it uses significantly less bandwidth (8kb). In low bandwidth connections, like dsl you might have a choppiness issue with g711. However g711 will provide you with significantly better call quality.
Should this be a configurable option in the Vestalink account settings?
I definitely think this should be an option in the Vestalink account settings. Many of us have plenty of bandwidth to deal with the increased demands of the g711 codec.
intelafone:
I am thinking that Vestalink should actually default to g711, because that's the only codec you can use with Google voice. So if you are GV user you will already have the bandwidth necessary for using g711. g711 sounds a lot better than g729. For now I am making g711 the preferred codec for Obi devices, we will implement a bandwidth saver option in the account settings that sets the default to g729. Thoughts, suggestions? Thanks
TonyTib:
I'm OK with either codec being the default, but I really like having both codecs available; the G729 seems to work better for me than G711 (based on calls made using Vestalink (G729) and GoogleVoice (G711)).
