[Serusers] call PSTN -> SIP

[smy at addm.com]

Hi all

I've done the same where SER can pass calls to my CISCO and Lucent EXCEL switch,
but when EXCEL tries to pass calls to SER (even when I placed the src ip into
the MYSQL trusted table), it seems like the call just hung there.  Also,
instead of using the default SIP port (5060), I have changed it to something
else since the internet in China doesn't provide 100% non-restricted
communications, they sometime block or filter ports & data.
Based on this, I have the EXCEL sent data based on my customized port (eg.
5000).  but when I view the /var/log/messages, it passes the call to my IP
PHONE using standard 5060 port.  How do I go about solving this???

Also, I'm using Mediaproxy for NAT environment, if calls from Cisco/Excel were
to sent to SER (while SER is authenticating the gateways via trusted table),
how would the calls be proxied and sent to an IP PHONE running behind a
router??  I need the calls to be proxied!  Does anyone have a solution for
this?!?  Please advise!!

Best Regards,
Samuel Yeung
