Hello,
I have a question regarding my ser.cfg. First let me explain our
situation.
I have a SER server (actually openser) behind a NAT firewall (Cisco PIX,
which is doing SIP ALG). The SER server has ip address 10.254.254.1
which is translated by de NAT Firewall to a public IP address. Behind
the SER we have a connect with a telco who provides us a SIP PSTN
gateway. It's IP address is 10.166.38.108 (so, also private).
Remote clients connect to our SER via the public IP address of the SER.
…
[View More]For this to work, I use RTPProxy for all sessions. So I do NO client_nat
tests or whatsoever. Most of the time, all calls go well. However
sometimes when a UAC retransmits INVITE requests, the retransmitted
responses display the wrong proxy-address (for RTPProxy). For example,
when the UAC does 4 INVITE request (so 1 request, and 3
retransmissions), 3 of the responses have SDP with 10.254.254.1 in their
body. The last one doesn't change the SDP address, but has 10.166.38.108
in its body. What could be causing this? Clients obviously don't get
audio in their conversation.
Next, since I wrote the ser.cfg by my own, it would be nice if some of
you could review my ser.cfg and, if needed, give me some suggestions
etc.
Thank you all very much in advance,
My ser.cfg:

Hi,
I am new to SER as our company previous administrator who looked after our SIP server has left the company and left no documentation.
Our server got restarted du to power failure and it is unable to start ser. This is what I am doing to start SER and I am getting following error.
/usr/local/sbin/ser -f /usr/local/etc/ser/ser_091105-noenum-full.cfg
and this is what I am getting in /var/log/messages file:
0(2772) parse error (81,38-39): unknown command, missing loadmodule?
0(2772) …
[View More]parse error (82,2-3): syntax error
0(2772) parse error (82,2-3): bad command
0(2772) parse error (82,4-8):
ERROR: bad config file (4 errors)
What I am trying to find out what is (81,38-39)?
is it line 81 column 38-39 or else also how can I fix this problem.
Please help me so I could get our phone system working again.
Regards
