[OpenSER-Users] How to add port=5060 to top Via?
by Iñaki Baz Castillo 03 Jul '08

03 Jul '08

Hi, OpenSer by default creates a Via with no port (if port is 5060): Via: SIP/2.0/UDP 88.99.3.10;branch=z9hG4bK87ab.47b6f072.0 Because problems in my carrier's softswitch SIP stack I want top Via contains also the port 5060. AFAIK I can force that port appears by using: advertised_port=5060 but it sets a fixed value (and in a future I want to listen also in 5061 for TLS and so). Is possible OpenSer to add the **real** source port to the top Via created by it? Thanks. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

Re: [OpenSER-Users] IP fragmentation but MB bit not being set
by Juan Pablo Fernandez 02 Jul '08

02 Jul '08

Hi Bogdan, We are using UDP transport for endpoints (xlite and Polycom IP 650) and TCP transport for our gateways (Avaya PBX with SIP support). Our proxy is record-routing and speaks UDP on the client side and TCP on the gateway side. In the client side, INVITE requests sent via UDP to the proxy are always small enough not to need fragmentation (at least for now). When the proxy adds Record-route headers, P-Asserted-Identity and some other headers, the packets length sometimes increases enough to need fragmentation. The problem was rather random but once we identify it we inserted a long custom header to reproduce it. We have been making some research and someone pointed out (thanks Tomasz Radziszewski)that in our case we are not having fragmented IP traffic but segmented TCP traffic, therefore there is no need to assert MF bit in IP flags. Because of the UDP/TCP reencapsulation we have 2 RR headers which add to the total segment length making it more prone to needing segmentation. Do you believe this is a problem in Avaya SIP implementation (Avaya CM/R013x.01.3.640.2)? Assuming the later, is there any possible workaround, may be a way to shorten SIP message body? Thanks for your help Regards Juan Pablo ----- Original Message ----- From: "Bogdan-Andrei Iancu" <bogdan(a)voice-system.ro> To: "Juan Pablo Fernandez" <juanpablo.fernandez(a)globant.com> Cc: users(a)lists.openser.org Sent: Tuesday, July 1, 2008 9:45:46 AM GMT -03:00 Argentina Subject: Re: [OpenSER-Users] IP fragmentation but MB bit not being set Hi Juan Pablo, usually this kind of fragmentation problems were an issue for UDP, but never found similar problem for TCP. Actually this the reason why the IETF guys want to obsolete UDP for SIP and keep only TCP... how is generating the packages ? what device? because more or less it will responsible for framing the content.

[Serusers] usrloc won't work after a couple days?
by lin9k＠yahoo.com 02 Jul '08

02 Jul '08

Hi, I have setup ser to run with mysql. At beginning, it worked fine that the mysql/ser/location table got the correct update. However, after 3 days the table won't get updated. When I enable the mysql log I cannot see any updating or inserting into that table. User registration is still working fine but just not get updated into the location table. Also, server_monitoring tables are working fine. Anybody run into the same problem? I am using ser-0.9.6. Another question is that how do I know the usrloc.so module is still loaded? Thanks, Ling
