SPA3000 as a PSTN Gateway to Asterisk

What is the best method of using SPA 3000 as a PSTN gateway for Asterisk ?
Should I enable VoIP-to-PSTN gateway feature of SPA3000 ? and what configuration to make on both (SPA 3000 and Asterisk)
Shoul I define SPA3000 as SIP Trunk ?

there are several examples on the web for this. Here is a good one: … &Itemid=26

I would make one modification, in their dialplan, replace ‘s’ with your incoming pstn phonenumber (did). This will have it come into Asterisk as a did and you can use inbound routing rules to send it where you want.


thank you
I’ll try it.
