[Serusers] rtpproxy bridge mode ip addresses used

by Shaun Hofer

I used examples/alg.cfg to set-up SER between two subnets (both private at this stage) and had the UA (end points) connected directly to SER machine, one to each interface. This all worked fine, but the problem I've found is that when I started putting UA onto other subnets I would loose the rtp packets. It seems rtpproxy uses one IP addresses and not both for sending rtp, when in bridge mode. This causes problems when the two subnets are non-routable except through SER and rtpproxy. UA (10.0.10.212) ----- (10.0.10.1) Router (10.0.100.1) ---- (10.0.100.2) SER (10.0.11.2) ---- UA (10.0.11.150) From packet captures I can see that UA 10.0.10.212 tries to send RTP packets to 10.0.11.2 which the router knows nothing about and doesn't route to 10.0.100.2, but the SIP packets seem to have the correct src and dest. I know I can put static routes in etc for the router. We hope to deploy this where the private IP address will be replaced by public ones, and there will be routers connected to one of SER machine's interface that we have no control over. Any ideas on how I can force rtpproxy to use 10.0.100.2 when going to 10.0.10.212 and still use 10.0.11.2 for 10.0.11.150 or is this limitation of rtpproxy ? netstat when UA 10.0.11.150 calls UA 10.0.10.212: udp 0 0 10.0.11.2:8016 0.0.0.0:* 19347/rtpproxy udp 0 0 10.0.11.2:8017 0.0.0.0:* 19347/rtpproxy udp 0 0 10.0.11.2:8018 0.0.0.0:* 19347/rtpproxy udp 0 0 10.0.11.2:8019 0.0.0.0:* 19347/rtpproxy udp 0 0 127.0.0.1:7000 0.0.0.0:* 19347/rtpproxy I have also tried swapping the -l ip address around, but still lost audio in one direction on calls. rtpproxy -l 10.0.100.2 10.0.11.2 -s udp:127.0.0.1 7000 Thanks in advance -- Shaun Hofer VoxPak Pty Ltd ********************************************************** If you receive this email by mistake, please notify us and do not make any use of the email.

Re: [Serusers] How SER communicate to other SIP server

by roayu

Hi, Olaf! I managed to call to the other SIP server. Unfortunately, both sides can't hear anything. What could be the problem? Could it be the NAT issue? If so, where should I allocate them to use the mediaproxy(before/after rewritehostport())? Thanks.

But you could also use t_relay_to_{udp,tcp} to specify a literal transport address where you want your request being routed to. <http://www.iptel.org/ser/doc/search> gives more information on these functions.

[OpenSER-Users] Presence, Database Error !!

by KUMAR

Hi all, I'm trying to make openser work with presence. I'm having few problems making it work. I've attached the openser.cfg that I'm using. The dump I get from the server is as follows. 1(5115) submit_query: Unknown column 'remote_cseq' in 'field list' 1(5115) db_insert: Error while submitting query 1(5115) PRESENCE:update_subscription: ERROR while storing new subscription 1(5115) PRESENCE:update_presentity: ERROR occured 1(5115) PRESENCE:handle_subscribe: ERROR while updating database 4(5125) ERROR:check_content_type: invalid type for a message 4(5125) ERROR: extract_body: content type mismatching 4(5125) ERROR: force_rtp_proxy2: can't extract body from the message Here's what the UA is doing. The UA upon registration is sending a SUBSCRIBE followed by PUBLISH. The server then forwards the PUBLISH. Now, Isn't the server supposed to send NOTIFY ? And what about the error messages resulting from the database operations ? Thank you in advance kumar

[Serusers] QUERY - SER Documentation

by Parminder.Nayyar＠relianceada.com

Hello This is in reference to the product SER available as a open source. We intend to use Solaris 10 OS as a SIP Server using SER. But I could just get the Getting Started article on the website which takes care of specific cases. However , can we get some documentation on the modules and parameters there in? Thanks Parminder Nayyar
