Hello y have 3 interfaces on my box 1 Lan to Internet 2 Lan to 192.168.1.x 3 Lan to 192.168.108.x I only have one domain in my openser I want to know a method to use the mediaproxy only when sending packet tru interfaces for example When making a call from lan 108 to internet or 192.168.1.x Im putting this kind of rules I set different number for number for each lan 1 for eth0 2 for eth1 3 for eth2 so each client has different number regarding the interface he sees .. Is this valid ?? if (from_uri=~"sip:|1[1]|2[0-9]|3[0-9][:@]" && to_uri=~"sip:|1[2]|2[0-9]|3[0-9]|4[0-9][:@]") { log("de 1 a 2\n"); use_media_proxy(); }; if (from_uri=~"sip:|1[2]|2[0-9]|3[0-9]|[0-9][:@]" && to_uri=~"sip:|1[1]|2[0-9]|3[0-9][:@]") { log("de 2 a 1\n"); use_media_proxy(); }; And not to use mediaproxy when calling within the same lan. Thanks for your help Fernando Rodriguez V. frod(a)aitelecom.net AITelecom S.A. de C.V. http://www.aitelecom.net

Hello all, very glad to have been a user on this list, though I have been lurking. I've checked the documentation and have had trouble finding out information on how to translate my standard regexes (perl) into SER's routing logic I'm trying to use the following logic: if (uri =~ "^sip:1[0-9]{10}\@[0-9]{3}\.[0-9]{3}\.1\.foo\.bar\.net") { #perform actions } Now, that SHOULD match the following scenario: uri has 1 + 10 digits + @ + 3digits + . + 3digits + . + 1 + .foor.bar.net Unfortunately, it's not working.Any help translating the regex, or even just a link to the syntax allowed, maybe it's not allowing {n} to match n times? Thanks, Sherwood McGowan

[Users] access control list using avps
by jayesh nambiar 28 Sep '05

28 Sep '05

hi all, I tried going through the avp documents but I have a few doubts related to avp_db_load and avp_check functions. I wanted to implement the access control list. the access control values may be jus like: 1 => local calls 2 => long distance calls 3 => international calls. I am using the default table usr_preferences. when I do the avp_check as: if(!avp_check("$acl", "and/0x01")) I get an error that it cannot be parsed and fix the avp_check. And can someone pls explain how the bitwise check "and", "or" etc works.. thanks, jayesh --------------------------------- Yahoo! for Good Click here to donate to the Hurricane Katrina relief effort.

[Users] business mailing list
by Daniel-Constantin Mierla 28 Sep '05

28 Sep '05

Hello everybody, a new mailing list was created to provide a forum for parties who wish to discuss commercial or business related activities, opportunities, etc. related to OpenSER, VoIP, SIP ... The email address of the mailing list is "business(a)openser.org". To subscribe/unsubscribe, follow the link: http://openser.org/cgi-bin/mailman/listinfo/business It is list where everybody can subscribe but no archiving is done. This should force anyone interested in some business to get up-to-date information, avoiding questions related to past mails found on web archive. Also, it should prevent some spaming from users trying to increase search engine's ranking via links and message posts. The usual mails sent to this list should be in the form of "I need _this_, who does it?" or "I do _this_, who needs it?", but should not be limited to such pattern. Basic rules for posting on the mailing list: - keep a fair conduit of messages, no bad remarks about others or counter-advertising - do not send images, flash or other graphics - post links instead - it is recommended to reply directly to the sender when it is a one-to-one business, the others may not be interested, otherwise they should post a message - if nobody answers, then nobody needs/provides what you offer/need, it is no reason to send the message hourly, wait for some days or weeks Hopefully, it will help everybody for a mutual benefit. Cheers, Daniel

[Serusers] How to terminate a session?
by Federico Giannici 28 Sep '05

28 Sep '05

Suppose that we know which calls are open, based on the accounting data, so we have all dialog parameters (Call-ID, From, To, C-Seqs, etc...). How can I terminate a session that is lasting too long? If I suppose that a session is actually closed (for example because one UA has crashed), how can I be sure that it is really closed (eventually actually closing it)? I'm thinking to send two BYE messages to both UAs (impersonating the other UA), so to make them close the session (if it is still open). Is this tecnically possible? Are there any contraindications? Is there a better way to obtain it? Thanks. -- ___________________________________________________ __ |- giannici(a)neomedia.it |ederico Giannici http://www.neomedia.it ___________________________________________________

[Serusers] Aliases and Location Problem... please help
by Ryan Pagquil 28 Sep '05

28 Sep '05

Hi SER users, Why does my aliases and locations are not persistent? Considering that they appear in my database (aliases and location), when I restarted SER all aliases and locations are not being read by SER. What will I do is to restart my X-lite softphone for me to re-register. And for my aliases I will run again serctl alias add <alias> sip:<uri> for the aliases to work. It seems like SER is not reading my database and all contact informations are only stored on its memory. But all these contacts appears in my location and aliases tables of the ser database. Is there any known bugs about this? Please help. I'm using SER-0.9.3 in SPARC64 Debian linux with mediaproxy as nat traversal solution. Any help is greately appreciated... Thanks, -- Ryan Pagquil Infodyne Inc. - PhilOnline.com 3603 Antel Global Corporate Center Doña Julia Vargas Ave. Ortigas Center Pasig City Tel: 687-0715 Web: www.philonline.com

[Serusers] problem detectec: Not found in usrloc
by Ángel Gómez 27 Sep '05

27 Sep '05

Hi, I have found the problem, but i don't know ho to solve it. To search the problem I started SER with a debug level 9, redirectin STDERROR to a file ( if some one want to do it is: /etc/init.d/ser start 2>>/ser.log1 ) and when I was reading the file I found it: 2(1926) lookup(): 'ninguna' Not found in usrloc This is what the server say when i send a MESSAGE to ninguna(a)10.22.1.249, but then I used: serctl ul show, and got this: ...Record(0x4045d1b8)... domain: 'location' aor : 'ninguna' ~~~Contact(0x4045d218)~~~ domain : 'location' aor : 'ninguna' Contact : 'sip:ninguna@10.22.1.249' Expires : 3583 q : Call-ID : '1549255136(a)10.22.1.5' CSeq : 1 User-Agent: 'sipsak 0.8.9_pre' received : '' State : CS_SYNC Flags : 0 next : (nil) prev : (nil) ~~~/Contact~~~~ .../Record... can any one give me a solution? BEFORE of sending the message I send a REFISTER for the user ninguna.

[Serusers] Adding Aliases for inbound PSTN
by Ashutosh kumar 27 Sep '05

27 Sep '05

Hi, I want to configure my ser.cfg so as to bind a user john to a DID 1234 from my pstn switch. John is a user in my ser DB and i want to assign him the phone number 1234, so that whenever my pstn GW forwards this call for 1234 to SER, SER should forward this call to user john.Which command do i use ni this case. serctl alias add john 1234, OR serctl alias add 1234 john, beacuse in my case, none of these is working, although i can see the switch forwarding the call to SER. How can i use save("aliases") in this scenario? I have used lookup ("alaises") at appropriate places. Thanks Ashutosh
