[asterisk-users] Linksys SPA-9xx Audio Issues

[Andrew Joakimsen]

Anyone else have problems with phones like SPA-922, SPA-921, etc?
Inbound audio is perfect but the remote end reports audio quality
issues on the audio the handset is sending out. It's not the
network.... I've tried asterisk 1.2, 1.4. I've used ulaw, G726, G793 &
G729. Ulaw seems to be the least problematic but its still an issue.
Doesn't matter if we send the calls to the PSTN via IAX or SIP or PRI.
I don't know it if happens all the time but about 40% of the time the
remote caller reports they cannot hear me.
