[Serusers] RE: voicemail - sr-users

20 Nov 2003

      Hi!
1. Please answer always to the mailing list, so others can help you too!
2. Your configuration is wrong! Are you using 2 ser proxies? If you want
to use redirect to voicemail after a certain time, you need 2 instances
of ser! The may run on the same PC. One ser instance is the main proxy
(register, forwarding, forward to the voicemail proxy after timeout) and
the other proxy serves the voicemail server. You should split your
configuration (as in the examples of jiri)
---
    # Voicemail specific configuration - begin
if(method=="ACK" || method=="INVITE" || method=="BYE"){
if (!t_newtran()) {
    		log("could not create new transaction\n");
    		sl_send_reply("500","could not create new
transaction");
    		break;
    	};
t_reply("100","Trying -- just wait a minute !");
    	if(method=="INVITE"){
    		log("**************** vm start - begin
******************\n");
    		if (uri=~"sip:as_welcome@.*" ||
uri=~"sip:as_nomoney@.*") {
                   		if (!vm("/tmp/am_fifo", "announcement"))
{
    		        	log("couldn't contact
announcement server\n");
    				t_reply("500", "couldn not
contact announcement server");
    			};
    		} else {
    			if(!vm("/tmp/am_fifo","voicemail")){
    				log("could not contact the
answer machine\n");
    				t_reply("500","could not contact
the answer machine");
    			};
    		};
    		log("**************** vm start - end
******************\n");
    	} else if(method=="BYE"){
    		log("**************** vm end - begin
******************\n");
    		if(!vm("/tmp/am_fifo","bye")){
    			log("could not contact the answer
machine\n");
    			t_reply("500","could not contact the
answer machine");
    		};
    		log("**************** vm end - end
******************\n");
    	};
    	break;
    };
-----------
This part must be in the ser.cfg of the voicemail proxy, not in the
ser.cfg of the main processing proxy.

I used the same thing in my config, but I dont know why it is directly
transferring to the voicemail. Can youplease see the attached 
ser.cfg in
this mail and please let me know where I'm doing wrong? That 
would be a
great help to me. Please let me know. Thank you very much.

Hi,
I'm trying to do the redirection to voicemail, but I was not
able to. Can
you please do me a favor? Can you please send me the section
of the code
that does the redirection to the voicemail? Thank you very much.

Subject: [Serusers] fr_inv_timer problem when using SIPPS
Hi!
I tried voicemail with redirect to the vm-proxy if the user
doesn't pick up
the phone after 10 seconds. It works fine if I call a kphone
user, but not
with SIPPS users. SIPPS sends a 180 Ringing every five seconds which
probably resets the timer - if I choose timer intervalls
shorter than 5
seconds it also works with SIPPS.
Is this a bug?
tried with ser:
0.8.12dev-t14
0.8.11rc1
0.8.11-r1
regards,
Klaus
