[Serusers] SER and RFC3325

by Gummadidala, Ravi

Does SER support RFC3325? Does it understand headers like "Privacy", "P-Preferred-Identity" and "P-Asserted-Identity"? If so, how can we specify the Spec(T) to control SER's behavior? Thanks, -Ravi.

[Serusers] call hunt

by Tulika Pradhan

i am tring to implement call hunt in ser 0.8.12 (no avpops). there is one problem. i am using exec_dset in the failure route as follows. failure_route[1] { exec_dset("/etc/ser/getnextnumber1 $SIP_OUSER; echo>/dev/null;"); append_branch(); t_on_failure("1"); xlog("L_ERR", "time [%Tf] method <%rm> r-uri <%ru> <%tu>\n"); t_relay(); } after the first failure, the SER sends 408 to the UA (caller) and it gets a busy tone. at this point, the second number of the call hunt group is ringing. but no voice can go through as the caller UA is showing 408 Request Timeout. please help, regards, tulika

[Serusers] Speeddial

by Aisling

Hello. I would really appreciate if someone could show me an example of how a speed-dialing entry should be added to the ser mysql database? E.g. If user 2092 dials 3 it rings user 3500. I tried : insert into usr_preferences (username, domain, sd_username, sd_domain, new_uri) values ("2092", "x.x.x.x", "3500", "x.x.x.x", "3") where x.x.x.x = ser address I have the following in my ser.cfg: loadmodule "/usr/local/lib/ser/modules/speeddial.so" modparam("speeddial", "db_url", "mysql://root:password@localhost/ser") modparam("speeddial", "user_column", "userid") modparam("speeddial", "sd_user_column", "short_user") modparam("speeddial", "sd_domain_column", "short_domain") modparam("speeddial", "new_uri_column", "real_uri") if ((method=="INVITE") && (uri=~"^sip:[0-9]{2}@.*")){ sd_lookup("speed dial"); }; I got a 404 not found, but its probably because I didn't create the entry properly in the mysql database. If someone could show me an example that would be great.

[Serusers] SER and rtpproxy in a DMZ

by Holger Moskopp

Hello, my name is Holger Moskopp and i'm Student at the FH Cologne. At the moment i'm working on my Thesis. I have to build a Firewall with DMZ and a SIP Expressrouter with RTPPROXY. This should look like this: -------------------------------------------------------- http://www.ganeymed.de/pixx/fw_ids/ser1.jpg -------------------------------------------------------- I'm in a Subnet of the FH and got on the I' in a Subnetz of the school and have installed on the computer xxx.22 fwclient a SER Registrar with RTPproxy and a Kphone softphone. On the internal SER there is a Kphone registered. (holleinnen). In the DMZ is a SER with rtpproxy. In the FH-Net there is a SER with Radius authentification and two softphones. Phil(a)xxx.73 <mailto:Phil@xxx.73> is registerd at that SER. holleaussen is registerd on another registrar that is not on the picture. If I want to call from holleinnen to phil, everything functions marvelously. The SIP signaling and the RTP-Traffic runs throuhg the DMZ. -------------------------------------------------------- http://www.ganeymed.de/pixx/fw_ids/ser2.jpg -------------------------------------------------------- Now to the problem: If I start a call from holleaussen to holleinnen the SIP phase , works perfectly thruh the DMZ. It rings inside and I can assume. After that nothing more happens. With tetereal and etheral I saw that the RTP traffic „wants“ to take the way directly from end to end. -------------------------------------------------------- http://www.ganeymed.de/pixx/fw_ids/ser4.jpg -------------------------------------------------------- Do you have an idea what is going wrong? I attached the two ser.cfg files because i think it is a mistake there. I tryed to fix that since 3 days now - but with no success. -------------------------------------------------------------- http://www.ganeymed.de/pixx/fw_ids/ser-dmz.txt http://www.ganeymed.de/pixx/fw_ids/ser-innen.txt --------------------------------------------------------------- Here is the relevant Firewallpart: $IPTABLES -N SIPLOG $IPTABLES -I FORWARD -p udp -i $DMZ_ETH --sport 1024:65535 -o $EXTERN_ETH --dport 1024:65535 -m state --state NEW,ESTABLISHED,RELATED -j SIPLOG $IPTABLES -I FORWARD -p udp -i $EXTERN_ETH --sport 1024:65535 -o $DMZ_ETH --dport 1024:65535 -m state --state NEW,ESTABLISHED,RELATED -j SIPLOG $IPTABLES -I FORWARD -p udp -i $INTERN_ETH --sport 1024:65535 -o $DMZ_ETH --dport 1024:65535 -m state --state NEW,ESTABLISHED,RELATED -j SIPLOG $IPTABLES -I FORWARD -p udp -i $DMZ_ETH --sport 1024:65535 -o $INTERN_ETH --dport 1024:65535 -m state --state NEW,ESTABLISHED,RELATED -j SIPLOG $IPTABLES -I SIPLOG -j LOG --log-prefix "SIPLOG: " $IPTABLES -A SIPLOG -j ACCEPT $IPTABLES -t nat -I PREROUTING -p udp -i $EXTERN_ETH --dport 5060:5062 -j DNAT --to $prox /(That changing only send the packets to prox but prox don#t take them: $IPTABLES -t nat -I PREROUTING -p udp -i $EXTERN_ETH --dport 1024:65535/ /-j DNAT --to prox) / I think a soulution could be to use the statefull iptabels filtering, but I don't like that solution. Thank you and best regards Holger Moskopp

[Serusers] No VM module and IVR plugin

by Nicky

Dear all, Please help. I am trying to download Sip_router_rel_0_8_12 and Sems version ser_rel_0_8_12 from the CVS but in the sems there is missing module for IVR. Then I try to download 0.9.0 version for both but there is missing VM module in Ser which is required to link to Sems. Please advice if I would like to use 0.9.0 version, without VM module how can link to SEMS and why in the sems version ser_rel_0_8_12 the IVR plugin is missing and where can I find it. Thanks in advance.... Regards, Nicky
