[cisco-voip] Delayed Voice - Troubleshooting Tips?

[Erick B.]

The UK end has the 7.1(1) phoneload from the filename
posted below. That load had numerous voice quality,
reboot, etc issues and was pulled from cisco. They
have released a new version out now, 7.1(2) which
fixes those issues present in 7.1(1). 

Does the delay happen on all calls or just some? Could
there be a routing issue between the phones perhaps
when the audio stream is cutting over? Is there a
firewall, etc between the US and UK that traffic goes
through?
