[Serusers] Creating a test scenario to test NATing..

by Piyush.Bansal＠relianceada.com

hi all, I wanna simulate a test scenario in which the sip clients are behind NAT (whether same or different NAT, in some private network), and the SER and MediaProxy are running on some public IP. My question is, in this case the client is not able to communicate with the server through the Firewall / NAT. My SIP messages are being dropped at the Firewall itself. Can anybody tell me, what could be the reason behind that????? I'm totally stuck at this point..... plz revert asap... thanx in advance..

[OpenSER-Users] openser + freeradius + cdrtool in freebsd

by Sam Wun

Hi, I found openser and freeradius in the freebsd ports tree, but the cdrtools is a tool for CD ISO in freebsd. Is this the right cdrtools for freesradius? In the CDRtools website, it said: http://download.dns-hosting.info/CDRTool/ "CDRTool provides mediation, accounting and tracing for Call Detail Records generated by OpenSER by using RADIUS protocol and OpenSER siptrace facility. " It seems that the CDrtools in freebsd ports tree is not the one for freeradius. Thanks W

Re: [OpenSER-Users] OpenSER with MySQL Cluster

Well, there is a trade-off between the complexity of a mysql cluster deployment and the possible inconsistencies introduced by t_replicate. With mysql cluster, you can always be sure that both of your proxies have the same, consistent view of the registration state. This comes at the prize of deploying and maintaining the db cluster. t_replicate is a lightweight replication mechanism that doesn't ensure registration state consistency. I like the simplicity of this approach. Personally, I prefer having a consistent registration state. I also think that the mysql guys have done a great job in making the cluster deployment and management as easy as possible. /Christian > > best regards, > /staffan > > >> -----Original Message----- >> From: Christian Schlatter [mailto:cs@unc.edu] >> Sent: den 19 september 2007 15:42 >> To: Kerker Staffan >> Cc: Juha Heinanen; users(a)openser.org >> Subject: Re: [OpenSER-Users] OpenSER with MySQL Cluster >> >> >> Kerker Staffan wrote: >>> hi >>> i'm curious about this one. we used to run a dual Openser >> installation >>> with MySQL cluster, but this proved to very unstable (on >> the cluster >>> side). >>> is this working fine now? >>> >>> for instance, if one of the mysql cluster nodes was >> disconnected, this >>> could lead to complete cluster shut down, and nodes didn't handle >>> reconnect very good. >>> >>> so, we actually switched to the register replication instead... >> We're running a mysql 5.0.22 cluster for our two redundant >> openser proxies.

[Serusers] Mediaproxy in public IP e two client behind same Nat

by pistara_bros＠tin.it

Hi to All, I'm investigating again about Mediaproxy and SER , but in this test i'm using the the testbed of smile.ing.uniroma1.it whic use SER and Mediaproxy in a public ip 151.100.122.144 I'm using Client_A (X- lite) running on WindowsXP 192.168.123.10 and Client_B (X-lite) running on WindowsXP 192.168.123.168 My Lan use a router with a public ip 83.211.41.253 So the clients are behind the same Nat. Using ethereal i see that during the conversation the RTP packet dont' pass through the Mediaproxy in public ip (151.100.122.144) but the packet go directly from one computer to another of my Lan. So the question is : what SER architecture (with Mediaproxy or with SEMS or other..) i have to use in order to have a proxy RTP that work as man in the middle and manage all RTP Traffic between the two clients? Please help me. thanks.

[OpenSER-Users] UAC module with Asterisk

by Halomoan Chow

Dear All Now I want to try UAC module to solve the proxy authentication to Asterisk. Until now it still fail even the username/password and realm are already correct 100% Then I found this statement "For sending authentication credentials to the termination provider openser has the "uac" module. But be aware that this module does not always works as it does not increase the cseq when sending the INVITE with credentials (search the archive for details). E.g. the uac module wont work if the termination providers uses Asterisk (as Asterisk checks the cseq)" Actually why UAC module has this limitation and why this does not get solved until now? Thanks Regards Halomoan Zhou

[Serusers] MeadiaProxy + SER + X-lite in the same Lan.

by pistara_bros＠tin.it

I want correct my previous posted sentences : "My guess is mediaproxy makes a test on the IPs (they are 192.168.147.2 and 192.168.147.3) and refuses to proxy the call." with "My guess is mediaproxy makes a test on the IPs (they are 192.168.123.168 and 192.168.123.10) and refuses to proxy the call." Does Anyone encounter this problem? could you share your opinion, with me?. Thanks. Orazio

[OpenSER-Users] memory allocation issue

by Benko

Hello! I wanted to upgrade a server from 1.1.0 to 1.2.2 today but despite extensive testing beforehand i have some trouble: After starting with the new openser-binary, it didn't allow any registrations and answered with "500 server error occured". Logging said: Sep 18 17:23:12 [/sbin/openser] ERROR: sip_msg_cloner: cannot allocate \ memory_ Sep 18 17:23:12 [/sbin/openser] ERROR: new_t: out of mem:_ Sep 18 17:23:12 [/sbin/openser] ERROR: t_newtran: new_t failed_Sep 18 and 17:23:12 [/sbin/openser] ERROR: sip_msg_cloner: cannot allocate memory_ Sep 18 17:23:12 [/sbin/openser] ERROR: store_reply: can't alloc' clone \ memory_ after restarting it with "-m 128"(according to the faq) these errors are gone, but it still doesn't accept registrations and prints: Sep 18 17:24:16 [/sbin/openser] ERROR:tm:print_uac_request: no shmem_ Sep 18 17:24:16 [/sbin/openser] ERROR:tm:t_forward_nonack: failure to \ add branches_ Sep 18 17:24:16 [/sbin/openser] ERROR:tm:w_t_relay: t_forward_nonack \ failed_ [update] - after several restarts, the first error-messages appeared again. When i run the new version on port 5061(old production server 1.1.0 is running parallel on port 5060) i can register with the new server(on port 5061) without problems. I have the vague impression that the new instance can't free memory, but why does it work when i run it on a different port? Any clues? Regards Christian

[OpenSER-Users] OpenSER with MySQL Cluster

by Vasile Zaharia

Hi *, Normally, OpenSER should work just fine with a MySQL Cluster, but I would like to know if anyone has tried this configuration yet. Are there any configuration settings I should be aware of? Thanks, Sica. ____________________________________________________________________________________ Take the Internet to Go: Yahoo!Go puts the Internet in your pocket: mail, news, photos & more. http://mobile.yahoo.com/go?refer=1GNXIC

[OpenSER-Users] Configuration of Permissions module

by Sergio Gutierrez

Hi everybody. Does anybody has any example about how to configure the permissions module to use address validation from database configuration tables? In our setup, we observe an inconsistent behaviour when defining subnets; fifo command subnet_dump does not show the expected subnet. The only case wich works well is wehn mask is set to 32. Thanks in advance for your attention. Sergio Gutierrez EPM Telecomunicaciones Medellin - Colombia
