Hi Jalal,
Using the SPA 3000 as a small PSTN gateway with the LanScape Centrex SIP proxy works well. However, we don’t have specific SPA 3000 configuration information for you.
Note: The link above to the SPA3000 pictures the original Sipura product. Your product might be the newer looking Linksys version. Same device though.
Basically you do this:
1)
Configure the SPA3000 to register with the LanScape Centrex SIP proxy.
2)
For incoming PSTN calls:
On the SPA3000, configure it to forward all incoming PSTN calls to the SIP proxy. If I remember correctly, you have to define a call routing entry on the SPA3000 to forward incoming calls to the SIP proxy.
All incoming PSTN calls will then be forwarded to the LanScape Centrex Sip proxy and the SIP proxy will then additionally route the calls to appropriate SIP devices in the VOIP domain as defined in the SIP proxy’s call routing configuration.
3)
For outgoing PSTN calls from the VOIP domain:
Configure the Centrex Sip proxy to have a single PSTN call routing plan. This will be a single regular expression entry in the proxy’s call routing table. When a dialed number from a SIP device is processed by the SIP proxy, the SIP proxy will check to see if it fits the dial plan for the SPA3000 gateway. If it does, the call will route to the SPA3000.
Performing a quick Google search revealed this document:

It may help you.
