The linphone registrar/proxy that coincides with your free SIP account 
does not bridge your calls to the public switched telephone network.

If order to make/receive calls to/from the public switched telephone 
network use a SIP service that supports this function.
Services that connect to the PSTN are usually not free.

I've seen this question many many times over the years.
Maybe Linphone could make it clear that their free proxy does not 
connect to the PSTN.
