Thank you for your reply

I commented out my section and replaced it with

if (does_uri_exist()) { # The called number is a local user if (lookup("location")) # The user is online { route(1); exit; } else { route(2); exit; } }

Now if I call a PSTN number I get too many hops, and if I do a local call to a user online it does not ring at the other end. Thank you.

Hi All

I am trying to achieve the following

1. User Calls a number

• If the number is 00+all numbers go to PSTN -> Else check if the

user is existent in our SIP Proxy user pool and act accordingly

What I achieved so far is the following

2. User Calls a number

• Route checks if the number is online if yes the call is routed

to him (route[1]) if not it send the call to PSTN if it is 00+[0-9] route [2]. This works fine for 00+[0-9] number however if 123456 is called and the user 123456 is not online, the call goes down through the conditional statements because it does not meet 00+[0-9] and I get an error "To Many Hops"

Use:

if (does_uri_exist()) { # The called number is a local user if (lookup("location")) # If user is online call him: route(CALL_USER); else route(VOICEMAIL); # Or send 404 }

In this way you will avoid sending out a call for an online user that is not registered.

Dear Inaki

Thanks for your help..I had the if statements wrong..can you please help me on how to send a 404 statement ?

But agian the same: Please, read the doc, read the cook-book, the pseudovariables page, the modules doc...

To be fair to Ali and all others in his predicament, OpenSER documentation - as much as has been put into the effort - *is* rather recondite and abstruse. It provides a lot of specification on how to accomplish particular tasks, but not really a whole lot of high-level conceptual overview or theoretical introduction to the mechanics of the engine, or why you would want to do various particular things.

OpenSER is wonderful, but it's one of the harder things to "get into" in the open-source VoIP space because its documentation is rather lopsided in this regard.

Hi Alex,

yes, you're right. I've added a link to the Rome admin course materials on the Wiki which has some information about the general configuration, and will ask Bogdan about to provide some other slides about the internal structure from the programming course.

[And yes, I realise that such a gripe is best addressed by making a thoughtful and original contribution to the effort - that's why there's a wiki, right?]

Exactly. ;-)

Hi Henning,

Just let me know what you have in mind, and I'll try to help.

Hi Bogdan,

i was refering to your slides from the OpenSER development course. Could you perhaps provide them on voice-systems.ro for downloading like the admin course slides?

Thank you,

Henning

Ali, OpenSer scripting is not easy, you should read more doc and understand it better before trying to do all your requeriments.

If a call does "too many hops" it mean that you send it out (t_relay) without chaning the RURI, so it comes back to OpenSer, again and again.

If you call a registered user and doesn't ring it's because the INVITE doesn't arrive to the phone, does it? have you verified it? This is a low level software, you cannot speak about "a phone doesn't ring", the question is: does the INVITE arrive to the phone? you can test it with ngrep, for example.

Thanks again ..I refered to the documentation and it worked..I have tried to find lookup("location")) to see what it does but I could not find it. In which part should I look for it ?

Have a look at the module doc. lookup() is from the registrar module: http://www.openser.org/docs/modules/1.3.x/registrar.html#AEN342

br, janosch

Thanks for your patience and help. It is working now but I am trying to understand my script better.
