Hi list ! I have a Problem with the appending of an rpid with the functions avp_load_radius(), append_rpid_hf(). In my Radius DB i have an SIP-AVP field which is filled with the Value rpid:[NUMBER] When i run manuall the Radius Reply-Query i get the correct value for SIP-AVP. Now, i reconfigured my ser.cfg so that an avp_load_radius() is executed after an incoming INVITE. My Radius is answering on the command and sends the correct SIP-AVP Value for the User. Now my Problem: I can't append the RPID or anything else to the SIP-Header after the answer from the Radius. So the call is going out without the rpid in the Header. Can anyone help me ? Here is the Configure-Snip: if (method=="INVITE") { # here comes the invite if (!radius_proxy_authorize("")) { # for the digest avp_load_radius it seems that i must use an proxy auth proxy_challenge("","0"); # and an proxy challenge if(!avp_load_radius("digest")) { # here i get the SIP-AVP from the radius log(1,"Failure with the AVP-Value\n"); # if it fails i'll get a message break; # go out } avp_print(); # print all avp's (this command is never executed :( ) append_hf ("Remote-Party-ID: 111222333\r\n"); # append this silly row - it is never executed append_rpid_hf("", ";party=calling;id-type=subscriber;screen=yes"); # append the rpid from SIP-AVP - and this command is also never executed break; # go out }; route(3); # go to route block 3 break; # end } I tried also this snippet without the breaks and proxy-commands but it doesn't work. I don't know what is wrong - please help me :s Thanks ! Dirk

Re: [Serusers] sems IP

by Samuel Osorio Calvo

SEMS is not directly listening to any IP, it relies on the co-located instance of SER to interact with the "IP world". The topology is the following: [SER A]<--IP interface-->[SER B]<=fifo interface=>[SEMS] SER A is the standard SIP proxy, and you can configure it to forward messages to SER B as it would be another gateway (t_relay, rewrite_uri|hos, |etc..) depending on some rules (such as a predefined prefix in the r-uri as is done in the examples). SER B is the front end for SEMS and has a different config file from SER A. It receives the messages from SER A and forward them to SEMS using t_write_unix() so SEMS can receive the messages. As depicted, the interface between SER B and SEMS is not an IP interface but a FIFO or UNIX socket interface (depending on your config files). You can have SER A, SER B, and SEMS running in the same machine or place SER A in one and SER B+SEMS in another. I hope it makes things clearer, Samuel.

The SER instance with ser.cfg runs in 172.25.97.19 The SER instance with voicemail.cfg runs in 172.25.97.18 SEMS is running in 172.25.97.19 and I want to change it to run in 172.25.97.18. How can I change that? Thanks, Llanos

Hi, It is the same fix I applied to my working copy when i started this thread. So, it has been running for a week now, no problems so far.

[Serusers] SER Question

by diarmuid.oneill24＠mail.dcu.ie

Hello, I am a student in DCU University in Dublin, Ireland, and i was down loading the SIP Express Router onto a Sun Blade and i cant seem to permanently set the environment variable "SIP_DOMAIN" to my localhost. I use the followng commands in the terminal to set the variable SIP_DOMAIN to the localhost and it works but when i reboot the Sun Blade and type in "#echo ${SIP_DOMAIN}" i dont get back localhost. If you have any solutions to this problem, i would be delighted to hear of them. #SIP_DOMAIN=localhost #export SIP_DOMAIN #echo ${SIP_DOMAIN} Regards, Diarmuid.
