i have a customer who is facing echo on intra-office calls - no echo otherwise.
I have updates the sip load to 322, forced codec to G711 and checked the settings as described in tech bulletin 16249.
Any other suggestions?
Attached to the ticket are 3 captures of the calls.
welcome to the Polycom Community.
I am unsure why you are referring to this post as a ticket as this community forum is not a replacement for the Polycom Support structure.
If you are using the correct and unmodified sip.cfg and phone1.cfg (not touching any of the volume affecting parameters) or are using the Broadsoft Platform to provision the phones then the Echo should not be introduced by the Polycom Phone.
I only had a quick look at the traces (to check the serial number of the Handset) and could not find any audio in the call.
Please raise this via your Polycom Reseller or work with Broadsoft.
