RE: OpenVPN phones have intermittent audio loss
James,

Thanks for the fast response! The call quality will degrade significantly at random points during a call. Some calls will work completely fine with no problems, other calls may start out fine and then degrade and then may recover again later if the call is long enough.

I will try holding the hold button the next time this happens.

Are there any settings on my gateway that I should attempt to adjust? I just tried lowering the MTU from the default 1500 to 1200 using "mssfix 1200" in my OpenVPN server config on the gateway yesterday.

Note that I have tried changing the Jitter Buffer settings from their defaults to the following, with no improvement:
Code:
Type: Fixed
Minimum Delay: 120
Maximum Delay: 120
Normal Delay: 120

Note that I am experiencing it on the following phones with the following firmware versions:
Code:
SIP-T38G        38.70.1.33
SIP-T32G        32.70.0.131
SIP-T42G        29.73.0.50
