Re: [Users] rewriteuser

by Daniel-Constantin Mierla

Hello, you can implement this with avpops module (http://www.voice-system.ro/docs/avpops/). Functions of interest for you are avp_write() and avp_pushto(). ... avp_write("1234", "s:client_n"); alias_db_lookup("dbaliases"); lookup("location); avp_pushto("$ruri/username", "s:client_n"); t_relay(); ... For optimization reasons, you may consider replacing the name of avp "s:client_n" to an integer id, e.g., "i:500" (faster operations).

hello, in SDP body sent out by the proxy the original media IP address is still present, the rtpproxy ip is added as a another line. is this the correct behavior ? should I add some flags to remove the original media IP ? for the invite this does not happen, the c= field is REWRITTEN with the ip received from the rtpproxy. message received by openser: ============================================ v=0. o=CiscoSystemsSIP-GW-UserAgent 4176 788 IN IP4 GW-IP-ADDRESS. s=SIP Call. c=IN IP4 GW-IP-ADDRESS. t=0 0. m=audio 17644 RTP/AVP 18. c=IN IP4 GW-IP-ADDRESS. a=rtpmap:18 G729/8000. a=fmtp:18 annexb=no. a=direction:passive. ============================================ message sent out by openser: ============================================ v=0. o=CiscoSystemsSIP-GW-UserAgent 4176 788 IN IP4 GW-IP-ADDRESS. s=SIP Call. c=IN IP4 GW-IP-ADDRESS. t=0 0. m=audio 35784 RTP/AVP 18. c=IN IP4 RTPPROXY-IP-ADDRESS. a=rtpmap:18 G729/8000. a=fmtp:18 annexb=no. a=direction:passive. a=nortpproxy:yes. ============================================ onreply_route block ============================================ if(status =~ "(183)|2[0-9][0-9]") { if(!force_rtp_proxy()) { log(3, "force_rtp_proxy FAILED"); }; }; ============================================ thanks Razvan Radu

[Users] one way audio problem with stun

by Diego Valencia

Hi everybody, I have a "one way audio" problem. My enviroment is: xx.xx.63.75/27 = SER xx.xx.63.68/27 = Natbox (linux iptables masquerade) xx.xx.70.2/25 = STUN server xx.xx.63.78/27 = PAP1 linksys AOR 2000 10.1.1.233/24 = PAP2 linksys AOR 2001 (behind NATbox with stun enable) I have no audio from PAP1 to PAP2 when the call is made from PAP1 to PAP2, but when the call is made from PAP2 to PAP1 it works correctly. I see on the natbox that the RTP packet is droped with unreachable cause (icmp messages). This is the trace (ngrep) for the call from PAP1 to PAP2 on external interface of the natbox, where I can see STUN packets and the number udp port that the PAP willl be use (16444 to 16447). The problem is natbox use other port (1173). I don't know if this problem is on natbox or stun server or PAP. Can you helpme? Thanks!!

[Serusers] Problem/Question regarding mediaproxy

by Ronald Voermans

Hello, I'm using Ser in combination with Mediaproxy. The situation is as follow: My SER has a private ip address (10.254.254.1), and my UAs also have private IP addresses, they can all see SER, and SER can see the UAs. Next, our company has a Voice Interconnect with a telco. (it's using Cirpack as softswitch). SER can see Cirpack and vice versa. However, the UAs cannot see the Cirpack. So I want to use Mediaproxy to overcome this. I can make outbound calls, but when calling inbound, I sometimes have one-way-voice of no voice at all. I think the problem is related to Cirpack, but I have a question thouh: - When calling mediaproxy, how does mediaproxy decide which one is the caller and which one is the called? Is this based on the From and To header? Because, if i call from PSTN -> SIP, i get serveral thousands (!) of messages saying that the called person signed in (no caller signs in in mediaproxy). This could be due to the fact that the from and to headers are incorrect. My ser.cfg is the one from onsip.org (pstn with nat). I can post configs/traces if someone needs them! Regards, Ronald

It looks like "allow_trusted" was removed from the permission module in CVS HEAD. Can someone confirm this? Or was it moved to a different module? Bjorn

[Serusers] SER + Mysql.so problem

by smy＠addm.com

Hi all, I've been working with SER + Mysql for over a month without any problems, yet all these (including the DB) are installed on the same server (LocalHost). I'm currently trying to centralize and securing all Data, thus would like to move all data to a centralized DB offsite. Now, I have SER DB migrated to this new DB server, and have changed the SER.cfg so that all mysql related loadmodule would be pointing to the proper server (ip address) instead of localhost. This is where the nightmare begins. The SER server can not seem to be connecting to the Mysql Server properly. Thus it took me over 3 days to debug and see if there were any auth problems from a remote site to the Mysql server. Apparently, remote auth & connect to the DB is working perfectly since I've installed other application which can connect to this DB server. So I've checked with the SER log + ngrep, of which to my amazement that the SER never sent any signals to the DB server. As soon as I moved the DB back to localhost, everything worked! My question is, is there something I need to configure in the mysql module so that it can work with a remote server???? Any insight is greatly appreciated!!! Best Regards, Samuel Yeung

[Serusers] accounting and radius/sql

by Bjorn Asmul

The best solution is to use two different tables for start and stop accounting. Have a look in the sql.conf file in FreeRADIUS Problem is that SER replaces the Username in the stop-message, with whoever hung up... Therefore the default queries in FreeRADIUS won't find the corresponding record. To get the CDR just join the two tables on AcctSessionId. I have experienced problems joining on the AcctSessionId in MySQL versions prior to 4.1, for some reason. Bjorn
