Linksys SPA3000 with UPC 3925 gateway

liamf

Hi

I have recently moved to UPC from eircom.
I have had an Asterisk setup at home for some time,and moving to UPC and migrating my home number was the push I needed to go the whole hog: get an SPA3000 and route incoming/outgoing UPC calls through my Asterisk server.

All is (almost) working fine.

However I have one issue: at fairly regular intervals, although the SPA3000 thinks that the PSTN line (i.e. the UPC line served up by the Cisco 3925 gateway they provide) is idle, the UPC gateway thinks that the SPA 3000 is off-hook. And as such, UPC don;t forward calls.

This is pretty annoying, and I reckon it is something to do with the line impedance (FXO Port Impedance) setting which I have set on the SPA3000.

I have tried either 600 (factory default for the SPA3000) or 370+620|310nF which I read someplace on the inter-webs was the correct setting for the UK - and so likely to be the same for Ireland.

Neither work 100% properly.

Anyone got any idea what the correct setting is? Or more accurately, why my Cisco 3925 thinks that the SPA3000 has picked up the line, when it thinks that it has not?

hmm

Still having this issue at irregular intervals (sometimes daily).

UPC box thinks the SPA3000 is offhook, SPA3000 thinks it is idle and onhook, weeping and gnashing of teeth ensues.

No-one got any ideas?

Ah feckit

Can't be bothered any more wondering how to fix this properly.

So instead I just run a python job now that fires up Firefox, logs into the various toys, checks their status to see if it's irregular, and if it is resets the SPA3000.

It has to do it in Firefox rather than in straight python because of the strange Javascript-driven UI on the UPC gateway.

Hey ho. Makes the problem go away. A hack, but a workable one.

Connect a phone to the ATA and press **** even if its a blank line then call RESET (73738) when you hear Configuration Menu and then dial 1. It will then reset and there shouldn't be any problems.

Thanks, I'll give that a go ... although I am about 99% sure that all my parameters are already factory default ...

Plus I have a selenium job which goes and kicks it now to wake it up again. So it won't stay permanently unusable ...

Best do the simple things first so the device isn't permanently changed by doing selenium jobs. The factory reset should fix it and is less complicated.

Let us know how you get on.

Dammit, it turns out my first problem is finding a working analog phone to plug into the thing ... I will borrow one and try it out

OK well, on the one hand, I didn't manage to scrounge up a working analog phone.

On the other hand, a job which looks at the UIs of the UPC browser and the SPA3000 and resets the SPA3000 if it is in an inconsistent state has ensured that the UPC line has stayed available for the last 10 days.

No noticeable downtime.
