[olug] Voip in CyanogenMod 7.1 audio delay. . .

[Christopher R. White]

I'm still playing sound with QOS controls and will report any findings on
the other suggestions.

As for the manufacturer lockouts, since this is an open build of Android and
not stock firmware, it's not likely locked out. . .

Google started this work with the development of 2.3, I'm running 2.3.4 as
of my last month update.

This issue also appears to be independant of phone model as most all Google
searches find different phones and firmwares but no real solutions. . .
Even the Nexus S with Google official 2.3.3 has a lag. . .

As I understand things, the sip service is ran at the kernel level as a
service
