Hello,
the error messages below indicate some problem with routing of replies, probably ser received a reply with just one Via. Make message dumps using ngrep and send them to us along with full config file.

I've seen other configs posted which appeared to be more strict than this, specifically they would only allow registered users to may calls, and not accept calls from anonymous sources to local numbers.
This above appears to work, sort of. While it doesn't allow anonymous callers to register, I think it's also not allowing them a chance to authenticate. The logs say
ERROR: forward_msg: no 2nd via found in reply (repeated a few times) Outside line (Indicating that the caller actually passed) route[2]:SIP-to-PSTN call routed ERROR: reply cannot be parsed
and repeat.
Any clues?
