Asterisk Lynksys SPA 3000 configuration

Asterisk Asterisk General
1

I bought a Lynksys SPA 3000 to make pstn out calls from asterisk.
All of our existing extension are connected to old pbx system. We are making only few phones connected to asterisk (for test purpose). So now i have a mix of asterisk connected extensions and old pbx connected extension.

My requirement would be, from asterisk phone i should be able to call the old pbx connected extension say by dialing 22(our system admin extension number). Also by dialing with prefix 0 i have to make outgoing calls say local mobile calls 0xxxxxxxxxx.

We have to dial 0 first in our old pbx connected extension, then we get a ring tone, after that only we can dial the local/std number we want to call.

Please advice on how to acheive this? All suggestion welcome.

Just did a quick test on our SPA-3102, it gives the dial tone if the * pbx calls it without any digit, so when you call the spa strips off any digit dialed and it should give you the dial tone, so something like this should be ok:

exten=>0,1,Dial(SIP/spa) ;spa is the peer name of the SPA-3102, defined in sip.conf

This was a nice piece of R&D work i ever did. Though it was very complicated at the begining (since i am not from any electronics or tele communication background), after lots of searching & reading & changing settings (trail and error) it WORKED!!! EUREKA :smiley:

Finally i didnt knew a small thing as [color=red]Line-In-Use Voltage[/color] under International Control section of PSTN LINE can turn to a nightmare :angry:

Almost the default factory setting will work for all. There are actually a few settings we have to do.

For India (Bangalore), these are the setting i did. I am not sure whether it will work for any other state/country.

(i created an excel doc to illustrate this, and incase anybody is having a hard time configuring then just mail me at [color=red]sanjith@optis.co.in[/color] and i’ll send you that document. I am no expert in asterisk, but this might save little time for you :smiley: )
