[asterisk-users] Rusting Snoms?

[Christian Stredicke]

Because the phone is a digital system, I would suspect that it is a problem with the switch. Run a quick PCAP trace to see where the jitter comes from. Depending on the firmware version, you can do that from the web interface.

Betreff: [asterisk-users] Rusting Snoms?

This is a bit off topic, because I 'think' it isn't an Asterisk problem.
However I'm not sure and anyhow I'm hoping someone may recognize the symptom.

We moved offices a month ago. Our trusty SNOM190s (all between 3 and 5 years old) were packed up for the move, then unpacked a couple of weeks later.

On unpacking them and connecting them to the new network, several of them didn't work well. The symptom is that outgoing RTP audio is garbled - like the packets are pulsed. Inbound is fine. This isn't true for all of the phones, just some of them. (The all run the same SNOM firmware)

To be fair, they are on a new network, so it could be the cables or new 1Gb switches, except that the problem moves with the phone if you relocate it from one desk to another.

I've tried a fresh asterisk install, but that didn't help either.

So I am forced to conclude that something went 'bad' in those
(old) phones while they were switched off. Has anyone got any clues for me?

Thanks!

Tim.
