[Serusers] SER/PSTN Gateway conf

[flavio]

Hi to all,
any suggestions about my issue?
I can reply with 200 OK to BYE messages send by Gateway, but SER does
not forward BYE message to SIP Phone.
( my scenario is the follow:

AnaloguePhone --> PSTN --> Gateway-->SER-->IP SIP Phone).

In the Handling NAT  example reported in GettingStarded doc, I've seen
that to tear down a conversation the end_media_session() parameter is
used.
Can I use this (loading domain.so and mediaproxy.so modules) in order
to handle BYE messages, without a really needs of mediaproxy?Is this a
good workaround?

Thanks for support,

Flavio
