Hi all, I have been plagued by an issue with my SPA-841 phones. The issue is that frequently, usually after a period of inactivity on the phone, an incoming call will be missed by the phone. The call works, cause the caller ends up at voicemail, but the phone never rings. I've managed to trap one of these missed calls in Asterisk, the log is below. Can anyone make sense of it?

Can anyone make sense of it?Might the SPA-841 be crashing and rebooting? With the current firmware (v. 3.1.4) I often see my phone hang and flash all its lights in the reboot pattern if it is the first time I've used in a long time. Often just trying to dial out is enough to push it over the edge. Sometimes on incoming calls it manages to hang in there for a minute or two and then it crashes in the middle of the conversation. (And no, asterisk doesn't clear the call until after the spa841 reboots.) -wolfgang -- Wolfgang S.

I experienced a similar situation with the SPA-841, it turned out to be that the calls I was missing didn't have caller ID (outside calls with caller ID Blocked), found that the SPA841 phone has an option to ignore calls without caller ID. Turned this option off and it fixed the problem. Sorry, I no longer use the SPA841 and I can't remember the exact menu setting on the SPA841 that fixed it, so you will have to go through the manual. c Message: 1 Date: Fri, 02 Dec 2005 21:43:01 -0800 From: "Wolfgang S.

Thanks all for the replies. I've narrowed it down to the phones dislike for my older 3COM switch. I noticed on the weekend that when these missed calls occur, if I ping the phone, the first few packets are dropped......almost like it's gone to sleep...... David A.

We ended up having to take the phone off our standard network. Even though it was a completely switched network, we believe sufficient ARP broadcasts packets were being sent to the phones to slow them down. Our symptom was choppy or "robotic" sound similar to what you'd expect with high packet loss, accompanied by extremely high "decode latency" numbers on the System page. Even that wasn't enough: we needed higher quality switches than the cheap ones we expected to be able to use, to avoid other sound quality issues which continued to crop up. This is good evidence as to why they didn't put 2 ethernet ports on the phone: it would only make things worse if you shared the port with a PC or workstation, I'd expect. Alan
