I have the following situation.
My provider gives me  PSTN connection  though linksys SPA 2102.They  connect SPA 2102 from imy side to their side by sip trunk.
In my side i have router with FXO ports.Now i`m trying to connect my  router`s FXO port to SPA 2102 FXS ports.
I`m truing to make call,but it  fails.Insted of  connecting routers FXO port ,i connect RJ 11 cabel from SPA 2102 to analog phone and make call.It succed.

My ISP said that it possible  to make call from  Routers FXO port connected with SPA2102 FXS port .ISP said that SPA2102 FXS port configured as default.

Can you collect the following debugs/information and send it over:-

Turn on the following debugs:

Make a test call

Also send me the show tech from the router. And the calling and called numbers for the call.
