Hello,
Unfortunately we cannot write the entire configuration file for you,
you should try yourself and ask for advice on particular problems,
then we can help you. Maybe somebody else on the list have similar
configuration and might send you the configuration script.
Also, read the following documentation:
SIP introduction:
http://iptel.org/ser/doc/sip_intro/sip_introduction.html
Dan Austin's howto:
http://iptel.org/ser/doc/ser-howto/ser-Howto.html
Administrator's guide:
http://iptel.org/ser/doc/seruser/seruser.html
SER Wiki page:
http://www.voip-info.org/wiki-SER+tips+and+tricks
The documentation covers everything you are going to need.
Also take a look at the mailing list archives because most of the stuff
has been covered already.
You can search through the archives using google. For example if you
were looking for mails related to accounting then you can type
"accounting site:mail.iptel.org".
Also make yourself familiar with the ngrep utility, the utility can make
dumps of SIP messages.
