Half Second Delay on Answer

[aapinedo1]

When anyone makes a call from one extension to another there is a short delay before the called party can be heard. This only occurs on internal calls and incoming calls from FXO ports are not delayed. I am running the latest version of firmware on the UC320 my switch is a ESW 520-24P and my phones are SPA504G. Is there any fix for this issue?

Thanks,

Hi Adrian,

Please install Disable_RTCP.pmf at Status->Devices->Alter PMFs in configure utility. Please apply the configure afterwards.

You can download this pmf at https://supportforums.cisco.com/docs/DOC-16301
