[Serusers] Timer Scenario.
by Atle Samuelsen 04 May '04

04 May '04

Hey Guys! First, thanks for a great mailinglist! How is it possible to either set maximum Reinvites when there is no "reply" from the device, Im am using RecordRouteing..? The reson why I want to do this is because If a user is temporary offline, I want to push him QUICK to a announcement. Anybody had this scenario before? and got an Idea on how to do this? I had 2 toughts, 1: Count invites, and set a flag, if f.eks some reply from phone etc, it will set counter to 0 again, and start looking for reinvites. This idea died because SER does'nt show me the reinvites it sends. 2: Use modparam("tm", "retr_timer2", 8), Tho this did'nt work for some werid reson. - Atle

Yeah first is solved... Second is if i have three users 111 222 333...111 called up 222 and they are talking with the beloew mentioned NAT file (as ser.cfg) if i make a call from 333 to 111 or 333 to 222.....both parties get RING.......if 333 called up 111 then 333 and 111 will get ring as if 111 is not busy...... >From: Jiri Kuthan <jiri(a)iptel.org> >To: "Kapil Dhawan" <sersavvy(a)hotmail.com>, serusers(a)lists.iptel.org >Subject: Re: [Serusers] Fork >Date: Tue, 04 May 2004 09:32:01 +0200 > >At 09:29 AM 5/4/2004, Kapil Dhawan wrote: > >Hi > > > >I am using the stable version of SER and rtpproxy....it is working fine >as such and i am able to get phones registered.....and can make >calls....Now....if i use fork=no with the same file....SER is unable to >process Register Requests... > >so set fork=yes > > >it does nothin for a register request...it just doesn't respond but for >fork=yes it works correctly....i know fork is used to fork the request to >more than one locations.. > >the config option 'fork' is unrelated to SIP forking, it is a debugging >mode in which >children processes are nto forked. > >-jiri > > > >Could u pls clarify it.... > > > > > >Second...i am using two grandstream phones and i can talk....but if i >make a call from third phone to any of two..instead of busy tone...i get >Ring...on the caller as well as callee side.... > >following is my ser.cfg > > > ># > ># $Id: nathelper.cfg,v 1.1.2.1 2003/11/24 14:47:18 janakj Exp $ > ># > ># simple quick-start config script including nathelper support > > > ># This default script includes nathelper support.

[Serusers] Fork

Hi I am using the stable version of SER and rtpproxy....it is working fine as such and i am able to get phones registered.....and can make calls....Now....if i use fork=no with the same file....SER is unable to process Register Requests...it does nothin for a register request...it just doesn't respond but for fork=yes it works correctly....i know fork is used to fork the request to more than one locations.. Could u pls clarify it.... Second...i am using two grandstream phones and i can talk....but if i make a call from third phone to any of two..instead of busy tone...i get Ring...on the caller as well as callee side.... following is my ser.cfg # # $Id: nathelper.cfg,v 1.1.2.1 2003/11/24 14:47:18 janakj Exp $ # # simple quick-start config script including nathelper support # This default script includes nathelper support.

[Serusers] PLEASE HELP very simple Dial plan (hotline feature)
by Humberto Atristain 04 May '04

04 May '04

Hello Guys Please help me with this issue I have 1 fxo gateway with each port registerd as a SIP user IP: 192.168.10.253 Port 1 : 201(a)192.168.10.253 Port 2 : 202(a)192.168.10.253 So on I have in the other side a Fxs gateways (eg 1 port each) Gateway 192.168.10.200 Port 1 : 101(a)192.168.10.200 Gateway 192.168.10.210 Port 1 : 102(a)192.168.10.200 I need a "hotline" feature if someone call to the por 2 in the FXO automatically calls port 1 in gateway 192.168.10.210 And if someone calls to the port 1 in the FXO automatically calls to 192.168.10.200 And also Viceversa If I pickup the phone automatically the gateway goes directly to the port 1 in FXO and that only port not port 2 BTW, please incluye where to put this block into the ser.cfg file Regards HA

[Serusers] using voicemail
by Andrea Bondavalli 03 May '04

03 May '04

Hi all, I am configuring SER in order to use the SEMS's voicemail when one of my subscribed users is not avaiable or when all the INVITEs to their contacts fail (fork). I'am using the following configuration: route { .... if (isflagset(4)) { /*voicemail enabled*/ t_on_failure("1"); } if (!t_relay()) { sl_reply_error(); break; } } failure_route[1] { t_reply("100","Trying -- going to voicemail"); if (method=="INVITE" || method=="REFER") { log("**************** vm start - begin ******************\n"); log("**************** voicemail ******************\n"); 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"); log("**************** voicemail ******************\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"); }; } ... This works fine when the system calls a user's contact whose username part matches the subscribed user name. Unfortunately, if the system tries to reach such a contact at a phone number (using a gateway) the result is that SEMS reports: "Error: 404 voicemail: no email address for user 034823213213." Can you help me ? Best regards, Andrea

[Serusers] presence xml format and SER

Hello all I have a question about presence xml document in SER. I would like to know whether this xml is based on any RFC or draft. I've been reading Presence Information Data Format <draft-ietf-impp-cpim-pidf-08.txt> and I have found nothing about <atom> element. Should UA support this element? Could you give some information? Thank you very much Curro
