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

by roayu

Hi, Olaf! Thanks for your reply. Could you please further explain on the connectivity between those to DIFFERENT sip servers? If I wanna call using a softphone to call from SER to SIPserver B, how should I make the call? Thanks.

[Serusers] Floating point exception

by bozhang＠nec-labs.com

Hi, I download the ser software and I can compile it successfully on my machine with Fedora core 4. But when I tried to run it with the 'hello world ser.cfg' configuration file, it reports "Floating point exception" error message. Any body had similar error before? or any idea what is happening? I tried to copy the compiled binary to other machines with FC4 , all gave me the "Floating point exception" error. any input will be appreacited! -Bo

Normally this should be sufficient. But better check to be safe. Please reply also to the mailing list, that others can see your questions and the answers too. Henning

[OpenSER-Users] multiple NAPTR records in ENUM module

by Jonathan Creasy

Is there a way to have OpenSER try each NAPTR record when multiple are returned? 4.3.2.1.5.5.5.5.5.5.1.mysite.enum. 0 IN NAPTR 100 15 "u" "E2U+sip" "!^.*$!sip:+15555551234@server2" . 4.3.2.1.5.5.5.5.5.5.1.mysite.enum. 0 IN NAPTR 100 10 "u" "E2U+sip" "!^.*$!sip:+15555551234@server1" . 4.3.2.1.5.5.5.5.5.5.1.mysite.enum. 0 IN NAPTR 100 25 "u" "E2U+sip" "!^.*$!sip:+15555551234@server3" . That would route the calls to server1 (order 100, preference 10) but if server1 is not responding I would like it to move on and try server2. -Jonathan

[Users] Malformed CANCEL request from Asterisk possibly impacting OpenSER?

by David Coulthart

We are currently experiencing problems with our production OpenSER (1.1.0) environment where the load on the server is steadily increasing and the OpenSER response time increases drastically (e.g., 30+ seconds for an internal call to ring). Capturing the network traffic when this happens we have noticed that our Asterisk (1.2.10) voicemail server is sending malformed CANCEL requests to our OpenSER proxy. We are not certain whether this is a cause or an effect of the load problems on the OpenSER server. Here is the SIP data from the bad CANCEL request: Session Initiation Protocol Request-Line: CANCEL :u43974@128.59.59.215:5069 SIP/2.0 Method: CANCEL [Resent Packet: False] Message Header Via: SIP/2.0/UDP 128.59.59.215:5069;branch=z9hG4bK6734835b;rport Transport: UDP Sent-by Address: 128.59.59.215 Sent-by port: 5069 Branch: z9hG4bK6734835b RPort: rport Route: <sip:128.59.59.199;lr=on;ftag=4FC702F4-7F812557> From: <sip:43974@sip.columbia.edu;user=phone> SIP from address: sip:43974@sip.columbia.edu To: "Jim Rios" <sip:47891@sip.columbia.edu>;tag=4FC702F4-7F812557 SIP Display info: "Jim Rios" SIP to address: sip:47891@sip.columbia.edu SIP tag: 4FC702F4-7F812557 Contact: <sip:u43974@128.59.59.215:5069> Contact Binding: <sip:u43974@128.59.59.215:5069> URI: <sip:u43974@128.59.59.215:5069> SIP contact address: sip:u43974@128.59.59.215:5069 Call-ID: c9a0135b-41273fb6-f7b6cea9(a)160.39.14.100 CSeq: 101 CANCEL Sequence Number: 101 Method: CANCEL User-Agent: Asterisk PBX Max-Forwards: 70 Content-Length: 0 Accompanying this bad CANCEL request are the following error messages recorded by OpenSER to syslog when it attempts to process it: May 29 15:34:07 cocoa openser[892]: ERROR: parse_uri: bad uri, state 0 parsed: <:u43> (4) / <:u43974@128.59.59.215:5069> (26) May 29 15:34:07 cocoa openser[892]: ERROR: parse_sip_msg_uri: bad uri <:u43974@128.59.59.215:5069> May 29 15:34:07 cocoa openser[892]: xl_get_ruri: ERROR while parsing the R-URI May 29 15:34:08 cocoa openser[892]: c9a0135b-41273fb6-f7b6cea9(a)160.39.14.100: route[0] CANCEL r-uri <<null>> from <sip:43974@sip.columbia.edu;user=phone> to <sip:47891@sip.columbia.edu> May 29 15:34:08 cocoa openser[892]: ERROR: parse_uri: bad uri, state 0 parsed: <:u43> (4) / <:u43974@128.59.59.215:5069> (26) May 29 15:34:08 cocoa openser[892]: ERROR: parse_sip_msg_uri: bad uri <:u43974@128.59.59.215:5069> May 29 15:34:08 cocoa openser[892]: loose_route: Error while parsing Request URI May 29 15:34:08 cocoa openser[892]: ERROR: parse_uri: bad uri, state 0 parsed: <:u43> (4) / <:u43974@128.59.59.215:5069> (26) May 29 15:34:09 cocoa openser[892]: ERROR: parse_sip_msg_uri: bad uri <:u43974@128.59.59.215:5069> May 29 15:34:09 cocoa openser[892]: WARNING: do_action:error in expression May 29 15:34:09 cocoa openser[892]: ERROR: parse_uri: bad uri, state 0 parsed: <:u43> (4) / <:u43974@128.59.59.215:5069> (26) May 29 15:34:09 cocoa openser[892]: ERROR: parse_sip_msg_uri: bad uri <:u43974@128.59.59.215:5069> May 29 15:34:09 cocoa openser[892]: ERROR: parse_uri: bad uri, state 0 parsed: <:u43> (4) / <:u43974@128.59.59.215:5069> (26) May 29 15:34:10 cocoa openser[892]: ERROR: parse_sip_msg_uri: bad uri <:u43974@128.59.59.215:5069> May 29 15:34:10 cocoa openser[892]: ERROR: parse_uri: bad uri, state 0 parsed: <:u43> (4) / <:u43974@128.59.59.215:5069> (26) May 29 15:34:10 cocoa openser[892]: ERROR: parse_sip_msg_uri: bad uri <:u43974@128.59.59.215:5069> May 29 15:34:10 cocoa openser[892]: alias_db_lookup: Error while parsing Request-URI While the malformed packet is likely the fault of the Asterisk server (we see no packets from OpenSER to Asterisk with the sip protocol missing from the URI), we are wondering if OpenSER errors out in a bad way when it tries to process this packet, possibly entering into some sort of loop that is causing the load to go through the roof. It is also unclear to us why the Asterisk voicemail server would be responding with a cancel. In our packet capture we see no record of a request initiated by the Asterisk server that it would be sending a CANCEL for. Any insight that could be offered into this problem would be greatly appreciated. Thx, David Coulthart

Hello Qiang, have you setup a mysql database and create the right tables with the database setup script? You find more informations about openser in the openser wiki on www.openser.org. If you want to use openser in a production environment, you should install a recent version, e.g. the latest stable release 1.2.1. Cheers, Henning

[Serusers] How SER communicate to other SIP server

by roayu

Hi, there! I would like to find out is there anyway that the SER server can communicate to other SIP servers? For instance, I have an account at SER and another account at SIPserver B. I would like to call from SER to SIPserver B, and vice versa. Is it workable? Or any additional devices needed in between these 2 SIP servers? If yes, could anyone give me some clues or guide to do so. Thank you. Best Regards, Roa yu
