Hi
@Mark: I agree, but some people only really need ser, or should I say if your route to much to asterisk its pointless having ser, I keep my Ip__IP traffic in ser, in fact my billing there also, asterisk as you mentioned for features, and when my upstream gateway wont support REFER to do transfers, and cool things like call pickup.
@Aisling: if (method=="INVITE"){ if(is_user_in("Request-URI", "voicemail")){ setflag(31); }; };
what this will do is to see if the username you have in RURI is in your grp table and has an entry of voicemail next to it, if so it will set a flag 31
if (method=="INVITE") {
avp_write("$from", "i:34"); if (avp_check("i:34", "eq/$ruri/i")) { if (isflagset(31)) { route(8); break; } else { sl_send_reply("486", "Busy"); break; }; }; };
what this does is basically to see if your are calling yourself, i.e if the from and the RURI is the same, first it stores the from setting, and the compares that to your ruri.Now if they are the same, it will see if flag 31 is set, i.e if you have voicemail attached to the RURI in grp table. If both are true then goto route8, at which point it seems as if your are relaying to another server.
You seem to be getting busy, which means that flag 31 is not being set, check your ngrep dump see what your RURI has, and see what entries your grp table has.
The problem with matching like this (or at least the problem(s) I had) was that there are alot of different call scenarios which all need to be taken into account.
EG my usernames are not e164 numbers, they are part of that number, which means my ruri, and from can be different to the e164 format. Now when a caller calls from 040600, to 0845040602, it should see if 0845xxx is busy, send to voicemail, but in grp ther is no 0845xxx, hence I need to make sure that the check/match is done after the alias lookup. I had to move lookup(aliases) near the to to make sure all my lookups had been done at the start, and then I can start matching.
Your best friend will be ngrep, if you start doing the diff call scenarios, and seeing what needs to be matched, you can set 1 run settings, once it all works work out a tidier logic.
If you throw asterisk into the loop, you add another headache (depending on what you do), cause asterisk was really designed for ip devices to register with it, but if you register in ser, you could lose some of that info (although latest beta, has some nice SIP header parsing, to pull info from).
The other problem you may hit with voicemail, depends on how you set your username, initially my subscriber table had names for username...eg Iqbal, and the alias would be 040600, or whatever, problem with this was that voicemail in asterisk is better with number, especially when you have to dial the mailbox number from your phone :-), so I switched the subscriber table to hold the number, cause I think unless you will be using software dialers, no one will type in names.
"voicemail=1:500;calltype=i:700;fwd_no_answer_type=1:701;fwd_busy_type
=1:702")
All this does is to define aliases, you can use it, or not

I see a lot of people trying to use SER and Asterisk together but mixing the roles in strange and complex ways.
Asterisk is an excellent SIP "feature server" and "b2bua" where SER is an excellent SIP proxy, registrar, and far-end NAT solution.
If you design your network based on those strengths you can create a solution that rivals 7 figure commercial solutions. People that do otherwise seem to just fall over themselves.

Many thanks Iqbal- That was the problem. I think the issue is that I don't even really understand what that line does or how the code that I took from Paul's config affected my config file.....SER now displays no errors but is still not working as expected. For example I expect that if a phone (e.g. 2092) dials its own extension, it should be caught by if (method=="INVITE"){ if(is_user_in("Request-URI", "voicemail")){ setflag(31); }; }; This then should be caught by the URI Compare code below and routed to route[8].... However that's not happening and a 486 Busy is being returned to the phone. I find this hard to troubleshoot because I think the code should be correct...given my current understanding anyhow... If Iqbal (or anyone else) has a clearer understanding of this and can shed some light on it, that would be great.
