Delay after call is picked up before the other party can hear you.

[EAdams2009]

IP Office v9.1, using netgear QOS/POE switches everywhere, phones are on their own VLAN. When a call rings into a extension (I think outside only, not 100% sure) the person answering has to wait for 1-2 seconds before saying hello, otherwise the other party wont be able to hear them say it. Its a really odd issue. Happens on our local in-office phones and remote VoIP phones we have at remote sites that are connected back to us via a VPN tunnel. No difference. Any ideas where I can start looking?

Try to hard set the codecs to G711 only on both SIP trunk and phones.

Is the G711 setting under the System or individual exts? I haven't had the system very long so Im a newb. If its on the ext Ill set it on 1 as a test first. Thanks

It has been an issue in an older release of 9608/11 phones.

If it is the phone release, is there a easy way to update the phones to a newer firmware and possibly fix it?

 

[derfloh]

Upload the firmware files along with the corresponding 96x1Hupgrade.txt and reboot the phone.

You can set the codec in the system settings.
