I've unplugged all my internal phone wiring, to get a better ADSL sync. This has left me with a problem; no phone in the lounge.

I *could* buy some cordless phones.. however, I have a Beaglebone Black idle and a tablet that lives in the lounge.

So, VOIP gateway -> Asterisk -> Android SIP client.

I know nothing about VOIP gateways, the Asterisks site mentions a Linksys SPA3102 - they're about £50 though. The older models, (SPA2102 ~£25) (PAP2T-NA ~£20).

They look like they'd be suitable, does anyone have any experiences of using these?
 
Could you not just fix your internal wiring? If unplugging all your phones makes a difference then you have a fault somewhere, either the cabling or with microfilters.
 
It's rented, wiring is all inside the walls and it 'works'. So no, that's not happening.
 
You shouldn't need to change the wiring. A filtered faceplate should be enough to isolate the extension wiring. That or just make sure the ring wires are disconnected.
 
I don't care. I want the setup I've described.

Edit: Sorry, that sounded a bit rude. I know how to clean up the internal wiring, but I don't want to. I don't like the corded phone and was going to get cordless anyway, but I know if I spend £30 on a pair of cordless phones that they won't be that good. I'd rather spend the money on a VoIP gateway and use our mobiles as clients.
I also get to learn about VoIP / Asterisk.

Hang on though, if you're going to plug a VoIP gateway into your line then you're still going to have to address the issue of the broken microfilter. All smartphone SIP clients are toilet compared to an actual handset, unless you purposely keep the phone awake and destroy the battery life in the process.
 
I don't have a broken micro filter, part of the problem is the master socket is in the master bedroom, and I don't want a phone there (other than mobile).

Anyway, on topic - Android SIP clients, are they that bad? Wifi can be kept awake, and the client can just run in background - it doesn't need wakelock and ruin the battery, else what would be the point in them?
 
Majority of mobile SIP clients aren't too bad but they do impact battery performance some what.

Having done a similar setup 18months ago (starting off with little knowledge), don't expect Asterisk to be a walk in the park as it can be a royal PITA at times and it took me a few months to get something (relatively) stable and setup to how i wanted.
In the end, i scrapped it due to a few niggles i couldn't solve (random reboot issue during high usage etc) and went with a provider.

It's certainly worth tinkering with/learning if you don't mind downtime on your landline but it's a bit of an over-engineered solution for the sake of a £15 cordless phone :p
 
Oh yeah, it's totally over the top - but then my solution to leaving the hot water heater on was to rig up sensors to it and have it alert me when I the temperature reaches a certain threshold..

Which VoIP gateway did you use, and what platform were you running Asterisk on?
 
If your looking to run Asterisk, try looking at PBXinaflash. Its an asterisk system with lots preconfigured so good to get going with.

I used to have that exact VOIP gateway you looked at and it worked fine. From what I remember though, it was a bit of a pain to get the settings exactly right but after it was setup it was faultless.

Thanks, will have a look. Which VoIP gateway did you use? The SPA3102 or SPA2102?

Just out of interest, how much better is the sync speed without the phone plugged in?

A few other factors were changed at the same time, but prior to removing the internal wiring, requesting a re-learn and changing the SNR margin it was syncing around 6500kbps, now I'm seeing 14000kbps (with a stable margin of ~1.5db).
