Does someone has a example with ENUM in SER?
I need to use SER with ENUM, but I think that the manaul in IPTEL is very sample and it
is not complete.
Sure, we use ENUM all the time for a lot of things.
The basic block I have is:
# Handle enum lookups
if ((uri=~"^sip:\+[0-9]*@*") || (uri =~
"^sip:\*164*@*"))
{
#log(1, "************ENUM BLOCK*************");
if(uri =~ "^sip:\*164*@*")
{
# Can't be in this format. Has to start with a +
strip(4);
prefix("+");
};
if(!enum_query("e164.arpa.") &&
!enum_query("e164.org.") && !enum_query("e164.info.")
&& !enum_query("enum.org."))
{
log(1, "Invalid enum? Route to PSTN");
};
log(1, "Valid ENUM number received");
# If we received a query reponse to any of those (in order)
route(1);
break;
};
All that basically does is take a number that starts with a + or a number that someone
dials beginning with *164 (our method of allowing ENUM access for people not on phones
that can dial a + symbol, and runs it through ENUM checks of 4 services.
You could take every number, route it through there, and if it doesn't match an ENUM
number, route it through other checks... thereby ensuring that ANY ENUM number is first
treated as ENUM and then, failing that, treated as a regular call, but dependent on the
speed of DNS and the ENUM servers in question, and where it lies in the chain, that could
slow call processing down quite a bit, so we don't do it by default.
