router foreplay

7aken

strange name for a thread i know but..............

has anyone come across a router (dsl probably) with which a firmware upgrade or some other type of script would allow the analogue port to be used as a connection for voip?

i ask because i have seen a linksys with two analogue ports, one of which could be used to connect a normal telephone and use it as a voip phone. not sure if it retained info to allow it to be used as a virtual sip phone but intriguing nonetheless.

so anyone know anything about this, im looking for a way to upgrade an existing router as opposed to buying a router with this functionality, no reason for this, just want to see if it can be done

What's the router model? Did you check the Linksys site?

would have been something like this, this wasnt the model i was playing with but similar. im really looking for a way to do this with an existing router as opposed to an out of the box solution. again, no reason for this apart from curiosity

That is the router I use as a router/ATA. Are you sure the one you are looking at isn't an ATA???

thats the idea im getting at, but is there a way to do this to an existing router

The router would need hardware to work as an ATA. It either is one or is not. Router information would help.

i think your missing the point, im not looking at any router in particular, im just curious as to whether you could add this funtionality to a router as opposed to buying an out of the box solution.

interesting that you say the router would need hardware to work as ata, whats the reason for this?

The port on a router is RJ45 whereas an analogue telephone uses RJ11 so some sort of physical adapter would be needed at the least, if the pinouts could be resolved.

I don't know enough about the technical details to be sure but the router port may using digital signals whereas an analogue port does not, different hardware would be needed for the different signals.

No it would be virtually impossible to do this. The router has some chips inside it that control the RJ45 ports. These chips are hardwired Ethernet controllers. The only way you could turn an Ethernet port into an Analogue Telephone Port is if you could take the Ethernet controller of the router's motherboard and put on an Analogue to Digital Converter (ADC). If you somehow managed to get that far and assuming the ADC did all the dirty work for you and spat out the audio as a nice RTP stream you'd still have to write a SIP stack for the router's firmware.

Even aside that it is virtually impossible that would be a hell of a lot of work and given that you could probably pick a router/ATA combo up off eBay for €20 to €30 it would be pretty masochistic!

while a dsl router would already have the required rj11, i agree that it would be a hell of a job to do this as opposed to buying a router with said functionality. once again though, im looking at this more out of the spirit of adventure.

The RJ11 port is not a problem. You can plug an RJ11 connector into an RJ45 port ok and use the middle 4 wires. It's controlling the electrical signal for those 4 wires (actually just 2 of the 4 you need for the phone handset) that will sink you.
