[OpenSER-Users] How to do =~ case insensitive?
by Iñaki Baz Castillo 18 Jul '08

18 Jul '08

Hi, I want to do a case insensitive match, for example for Privacy header that can contain "id", "ID", "Id"... and other values. I need something as: if ($hdr(Privacy)=~"id"/i) { but this obviously fails. Which is the way to do it? Thanks. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

[OpenSER-Users] Openser and mysql script
by Yann Derichard 18 Jul '08

18 Jul '08

Hi, I am using Ubuntu 8.04 and I have just installed Openser 1.3.1 via debian package (with mysql and presence modules) to do presence with my computer but I am not able to find "openser_mysql.sh" script to configure my database. So I downloaded the src package on openser ftp and unpack it but the script is still missing. Is someone could tell me where I could download it ? Or if I did something wrong during my installation ? Regards -- Yann Derichard

[OpenSER-Users] Limiting maximum number of concurrent calls
by Rana Dhekial 18 Jul '08

18 Jul '08

Hi, We are running openeser version 1.2.2. Currently we have defined 3 groups of subscribers. We have a requirement of limiting max number of concurrent calls per group. For example, 10 maximum number of concurrent ( incoming /outgoing ) calls for subscribers belonging to group 1. How do we go about it. Any sample config will be appreciated. thanks, dhekial _________________________________________________________________ With Windows Live for mobile, your contacts travel with you. http://www.windowslive.com/mobile/overview.html?ocid=TXT_TAGLM_WL_mobile_07…

[OpenSER-Users] OpenSER sending BYE to private IP behind NAT
by George Lee 17 Jul '08

17 Jul '08

Hi Experts, I have one SIP UA on private IP behind NAT and another 1 on public IP. They both registered to OpenSER and they could call each other. The problem is on call release. The BYE message sent from the UA on public IP could never get to the other UA on private IP. OpenSER kept on sending BYE to the private IP instead of sending it to the external NAT IP. I tried to use fix_nat_register() and fix_nat_contact() when REGISTER was received from the UA behind NAT but it didn't work. I also tried putting fix_nat_contact() on BYE and still no help. Am I missing anything? modparam("nathelper", "received_avp", "$avp(s:rcv)") . . . . . if (method == REGISTER) { if (nat_uac_test("2") || nat_uac_test("16")) { fix_nated_register(); # or fix_nated_contact(); } } . . . . . if (method == BYE) { fix_nated_contact(); } Thanks, whglee

[OpenSER-Users] Saving real IP:port using fix_nated_register()
by George Lee 17 Jul '08

17 Jul '08

Hi Experts, In my openser.cfg file, I tried to use the fix_nated_register() function to save the IP:port information when a REGISTER message is received. After I restart OpenSER, none of my SIP UAs could register to it anymore. Network traces showed "port unreachable". Can someone help? Thanks, whglee

Re: [OpenSER-Users] Does OPENSER support AAAA record (IPv6)?
by Fangyu Ling 17 Jul '08

17 Jul '08

Hi Klaus: Thanks for your answer. After I add dns_try_ipv6=yes in openser.cfg, my problem has been solved. But I wonder why the default value of dns_try_ipv6 is "yes" in version 1.2.x, but "no" in version 1.3.x? For my personal opinion, setting default value to "yes" is better than "no".

[OpenSER-Users] Using t_replicate to replicate towards a UA
by Pascal Maugeri 17 Jul '08

17 Jul '08

Hi Is it possible to replicate incoming SIP requests (eg. REGISTER) to another remote user SIP URI instead of host URI: For instance I want to do (having previously registered to OpenSER the user pascal.maugeri(a)company.com): t_replicate("sip:pascal@company.com <sip%3Apascal(a)company.com>"); instead of t_replicate("sip:10.2.3.4:5060"); I tried it with OpenSER 1.3 but I get the error message when it tries to replicate: 3(8113) Main routing block. Method [REGISTER] 3(8113) ERROR: mk_proxy: could not resolve hostname: "company.com" 3(8113) ERROR: uri2proxy: bad host name in URI <sip:pascal@company.net<sip%3Apascal(a)company.net> > 3(8113) ERROR:tm:t_forward_nonack: failure to add branches I'm just wondering if what I want to do is possible ... Regards, Pascal

[OpenSER-Users] O'Reilly Media is looking for contributors
by Kristian Kielhofner 17 Jul '08

17 Jul '08

Hello OpenSER Users, O'Reilly Media has been working on an Asterisk Cookbook. Using the same printed format as other O'Reilly Cookbooks (Perl, Python, etc) O'Reilly Cookbooks offer practical solutions to problems in a fun "recipe" format. I myself have been working quite a bit with OpenSER in the last couple of years and I've asked the other authors if we should open up submissions for other recipes (including OpenSER). Everyone thinks it's a great idea. We are looking for a potentially new name and URL but the current "Asterisk Cookbook" Wiki can be found here: http://www.asteriskcookbook.com/ We'll be covering "Asterisk and friends". That means Asterisk, OpenSER, Cisco gateways, etc. Pretty much anything VoIP with at least an Open Source slant. Request an account and add your recipes to the recipe heap (you'll see my OpenSER recipes towards the bottom). See you there! -- Kristian Kielhofner http://blog.krisk.org

[OpenSER-Users] Problem with accounting in case of call forwarding from client
by Ruchir 16 Jul '08

16 Jul '08

I have problem with CDR manipulation in case of call forwarding from client. I'm testing with Linksys pap2 and I've set unconditional call forwarding. When linksys receives the call, it'll send 302, temporarily moved. I have done proper ACL checking using Diversion header in the new INVITE but I'm having difficulty associating the forwarded leg CDR to original call as this is totally new INVITE and none of the fields match in CDR. Can anyone guide me in right direction?
