Tobias, Thank you for your time and explanation. For =~ what does this mean? Does the = means something particular, and then does the ~ means something particular as well? Also one last thing, what does the ^ mean?
Thanks again, Troy

I'm far from an expert myselfe, but here goes.. (inlined in your text..):

McAvan, Troy-P29897 said the following on 2006-03-14 19:32:
Would it be possible for someone to explain what each line means? if(method=="INVITE")
- If the SIP request method is an "INVITE", proceed with the code between { and }.
{ if(uri =~ "^sip9.*@.*")
- If the URI-field in the SIP request starts with and is like <sip9><anything>@<anything> proceed.
{ rewritehostport("ipofmediatrix:port");
- Rewrite the host and port part of the SIP uri, eg. this is what I would like to do to for example forward this INVITE to another destination.
if(!t_relay())
- Relay the message to the new destination specified with rewritehostport(). Remember this SIP-conversation and statefully inspection of all the following messages (transactions) following this INVITE (read more about t_relay in the "tm"-module README-file). If there is an error in any of the following transactions (eg. a 404 Not Found SIP message), proceed with this code snippet.
{ sl_reply_error();
- Replay statelessly with the errormessage found in t_relay (in my example, 404 Not Found).
}; };};
I am not a software guy and it would be great if someone could explain it line by line possibly.
