Re: [Users] Proxy/Registrar and NAT
by Bernie Hoeneisen 09 May '07

09 May '07

Hi Klaus, Alex et al. I was thinking about the same problem. My setup has two redundant SIP Proxy/Registrar (OpenSER 1.1) Servers (P1 and P2), no additonal edge proxies. It uses either MySQL cluster or Master-Master Replication to exchange the state of the location table. For NAT Processing of REGISTER I use the Nathelper module, which writes the original (inside NAT) address to the 'contact' column and the information, where the REGISTER request was received from (outside NAT socket) goes to 'received' column of the location table. e.g.: contact column: sip:behoe@192.168.1.56:2051 received column: sip:130.56.88.20:5432 When an INVITE arrives at P1 (or P2), the 'contact' column will go to the R-URI and the 'received' value will be used as the next target of the INVITE request. INVITE requests that do not arrive at the proxy, where the UA has registered, have (depending on the NAT type) some likelihood to fail. Appart from that and as long as there is no path value saved in the location table, this work fine. If there is a path value, its content will go to the Route header field and the the request is sent to the topmost Route entry. Therefore it looses the information that was stored in the 'received' column....:-( The preserve this information and to make sure that LL requests are routed via the proxy, the UA has registered to, I have some idea, that uses path. (Unfortunately not all of my UAs support 'outbound'...:-( ): When the REGISTER arrives at the Proxy P1, I would insert a Path header field with the address of P1 (i.e. the IP address and port of the proxy processing the request) Furthermore I would add a new header field parameter to the contact header field (let's call it "extsock" for the time being) containing the external NAT socket (i.e. the same information that also goes to 'received' column) e.g. Path: <sip:136.59.10.85:5060;lr>, Contact: <sip:behoe@192.168.1.56:2051;extsock=sip:130.56.88.20:5432;lr> This will then be stored in the 'path' / 'contact' columns of the location table at save(). When the INVITE arrives e.g. at P2, it does the location lookup: The Route header field will be populated with the content of the 'path' column and the R-URI will be rewritten with the 'contact' column. This means the request will be normally forwarded to P1 (topmost Route). The SIP INVITE looks e.g. as follows: INVITE sip:behoe@192.168.1.56:2051;extsock=sip:130.56.88.20:5432 SIP/2.0 Route:<sip:136.59.10.85:5060;lr> [...] After the request arrives at P1, it checks, whether there is an extsock parameter in the R-URI, and if yes, it uses its values as the next target of the request i.e. sip:130.56.88.20:5432 (Maybe P1 could even remove the extsock parameter from the R-URI at this stage to make some Nokia E-Series' phones happier...) My questions: - Is this idea feasible? Does it work in any case? Any issues with forking? - Could it easily be configured to OpenSER, or is there a change in the source code necessairy? - How much does it break SIP standards? ;-) Looking forward to your feedback. Have a nice weekend! cheers, Bernie > On Wednesday 02 May 2007 08:33, Klaus Darilion wrote: >> Hi Alex! >> >> Without having done this: You can configure the SIP proxies as load >> balancers too which distribute the load over all the proxy/registrars >> (including itself). > > I thought of that, but then every REGISTER needs to be forwarded to another > proxy to get the path info right.

[Serusers] Which version of SER to use?
by lists＠infoway.net 08 May '07

08 May '07

We are planning on deploying a couple of SER servers and integrate them with either SEMS or Asterisk for voicemail. However, we are a bit confused as to which version of SER to go with? From what we can tell, the latest stable version is 0.9.6. However, we know of the new 0.10.X version. Reading up on the site, there is some documentation that explains a little bit of the differences and/or migration recommendations/steps. So, in an effort to keep life as simple as possible, which version should we work with? We are afraid that if we go through a learning cycle with 0.9.6 we're going to "suffer" when migrating to the new version, either because of the learning curve or because of a potential painful migration process. Any recommendations? Thanks

[Serusers] Clueless newbie question - integrating SER and Asterisk
by John Breen 08 May '07

08 May '07

Help! I've followed the SER documentation and searched the web like a mad thing and found nothing useful. I have an asterisk box here at home and want to put SER on it so I can use SIP clients out in the real world (on the other side of my firewall) to get to it. Now, I have got SER set up and the phones register fine and everything, BUT I cannot see how to get it to pass calls through to Asterisk. I'm not using Asterisk realtime or anything like that - just plain old asterisk with plain old config files. I thought I had it right, but calls are just not getting to asterisk so far as I can see. I know it must be possible, I just can't see how to do it. Regards John Breen

Hello, using ser 0.9.6 The following dialog is a re-invite, the re-invite is initiated by the callee after putting the call on hold. Problem is that SER answer with a 407 on the wrong port, Invite is coming from port 62907 and SER answer to port 5060. Problem doesn't occurs for the initial invite. We have tried with other Uas without problems, just having problems with this Ua (Avaya). Any idea?

RE: [Users] lcr: load_gws(): from_uri to large

Hi Juha, Exactly this is my point, 128 should work and 129 should fail, especially since all related char buffers are allocated properly with size [MAX_FROM_URI_LEN+1] I think that the bug is here: if (from_uri.len < MAX_FROM_URI_LEN) { strncpy(from_uri_str, from_uri.s, from_uri.len); from_uri_str[from_uri.len] = '\0'; } else { LOG(L_ERR, "load_gws(): from_uri to large\n"); return -1; } It should be if (from_uri.len <= MAX_FROM_URI_LEN) George > -----Original Message----- > From: Juha Heinanen [mailto:jh@tutpro.com] > Sent: Monday, May 07, 2007 5:44 PM > To: Papadopoulos Georgios > Cc: users(a)openser.org > Subject: [Users] lcr: load_gws(): from_uri to large > > Papadopoulos Georgios writes: > > > I get the following error from lcr module > load_gws(): > from_uri to large > This happens when the rpid is exactly > 128 characters long.
