kudos:1 | I'll take a stab at it. The normal Packet8 residential service defaults phone calls to the g.729 codec. Except for faxes which default to g.711. g.729 is a much more dependable codec compared to g.711. G.711 is technically better quality, but most people can't tell the difference, it doesn't play as well with jitter, and depending on the person's bandwidth availability it can be too much for your system. Plus, some people's phones, Vonage and others, actually sound worse using g.711.
Now, I've only had Packet8 for 8 months, but from what I've seen with the prior 2 "unlocked" (For lack of a better word) version of Packet8's firmware, while you could select g.711 as your number 1 choice codec, that only guaranteed that you could initiate a call using the g.711 codec. The default codec for incoming was g.729. That is what the checkbox next to the g.729 was for. Even if you unchecked it, changes don't apply until you reboot, and upon rebooting the box became rechecked. Somewhere in the firmware it must have had a signal to keep that codec selected for incoming. I don't know. Thus any incoming calls negoticated at the g.729 codec.
Now, supposedly on this newer version, when you uncheck the box next to g.729 it stays unchecked and therefor all negotiations are based on the order of your choices. i.e. If g.711u as your first choice then that is what it will negotiate at unless the other end can't then it works down the order. Doesn't matter if it's inbound or outbound calls.
Why the past versions couldn't do it both ways and the newest version can, I have no idea. I am definately not the guru of firmware. I'm just theorizing based off the last version and what anonymous wrote in the above paragraph. I could be wrong, but at least it sounded good. LOL!!! Later... Mike.... |
