Issue with SPA 962 Phones

[John]

Hello,

 

we are facing the following issue with 6 Linksys SPA 962 devices. About 1 in 5 calls, whether incoming, outgoing or even between extensions have no audio at all. The phone of the called party rings (so the signaling is OK, even though the caller cannot hear the ringing tone while the phone of the called party is ringing) but when the call is answered, both parties hear nothing.

 

The problem is caused by the phones, because I replaced one with a yealink device and the yealink worked without issues. I have spent a lots of time so far experimenting with various settings without success.

 

Has anyone encountered a similar issue? Do you have any ideas or suggestions?

 

Thank you very much in advance,

John

I would record the PCAP for that extension. Maybe it is a just problem with the firewall.
