[OpenSER-Users] Openser as a conditional stateless proxy

by Padmaja

Hi all, Can any one tell me if the same running instance of Openser can be configured as a stateful proxy for some user accounts and for some numbers like emergency services, it acts like a stateless proxy, just forwarding the request to the destination?

[OpenSER-Users] dispatcher with GeoIP

by Victor Sergeev

Hello, I'm wondering if its a good idea to tie dispatcher module with GeoIP. The point is to select gateway group depending on IP from which user making a call. In such way you can select the gateway which should be closed to the user. E.g. some users will use USA gateways another EU or Asia gateways. Victor

[OpenSER-Users] CPL and XML schema

by Daniel

Hi everybody, Is it possible for OpenSER to use XML Schema for CPL instead of DTD file ? It would be more interesting use XLM schema, isn't it? Thanx daniel -- Daniel Grotti ________________________ e-mail : d.grotti(a)gmail.com

[OpenSER-Users] Announcement: devel.openser.org available

by Henning Westerholt

Hello, i'm happy to announce that the 'devel.openser.org' server, sponsored from my company 1&1 Internet AG, is now available. This machine hosts services for developers, but some of them are probably also useful for users: 1. Daily creation of debian builds (etch i386 and amd64) of the trunk for easily testing. 2. A read only svn mirror of the complete repository for better subversion performance especially outside the USA. 3. The build and testing framework "buildbot" for continous monitoring of the status from trunk and branches. 4. Doxygen code documentation with graph generation for better understanding of the code and module dependencies. You'll find at http://devel.openser.org/ the indivdual addresses of the services. This page will probably be moved to www.openser.org after the migration of these server.

Re: [OpenSER-Users] retransmissions after final response

by Vasile Zaharia

Hi Bogdan, all, I've made more digging and I need your opinion on my findings. Pre-condition: run an AS in forked mode with 2 children. 1. AS sends a request (RQ). 2. AS receives a "408 Request Timeout" reply (RPL) for RQ. 3. After some time (about 30 seconds) AS receives another "408 Request Timeout", initiated at another network node. 4. At this point, you want to send another request from AS. Result: Very often, the replies for the last request cannot be matched with its transaction in "tm" module, so request retransmissions occur. After a few days I've found that in "t_reply_matching" function from "t_lookup.c" file, just before returning (at the end of the function, not in the case when the reply gets matched) T is set to zero (set_t(0)). So, at step 3, the reply cannot be matched with an existing transaction and T is set to zero in a child process. If a reply of the request sent at step 4 gets handled by exactly the child process that last set T to zero, the transaction will not get matched (see t_check() and reply_received() functions), so the retransmission timer will hit => request retransmissions!!! I think the problem is that T is set to zero in t_reply_matching() when a reply cannot be matched. I've changed that to set_t(T_UNDEFINED) and everything seems to work just fine. What do you say Bogdan? Is this change safe? Is this the fix for my problem?

[OpenSER-Users] Cellphones and voicemail

by Chris Heiser

Trying to send a user's call to their cellphone can be problematic, especially when their phone is off, bad signal, etc... I know some carriers send q931 messages back when a call is redirected (sometimes), but not all do. Is it possible to make a determination in OpenSER (if we know we're sending to a cell phone) that the call was picked up too quickly? That's really the ugly problem. If I could say, "Oh yeah, you're cellphone picked up in less than 1 second, a real person probably didn't do that." and drop that fork, that would be awesome. --Chris

[Serusers] Anyone doing something to handle RFC3326?

by SIP

We've been looking recently at RFC 3326 (Reason header fields for SIP) primarily to help with logging in some of our UAs. While I know that SER can essentially tack on any header anywhere, I'm wondering if anyone's come up with a solution for handling something like the Call Completed Elsewhere reason tag: Reason: SIP ;cause=200 ;text="Call completed elsewhere" Essentially, this would be sent in a CANCEL message to all clients that did NOT pick up the SIP call. Since SER forks off a separate INVITE to any contact in the location table matching the intended recipient, it would be nice to fire off a reason for a cancel to some UAs which would then know not to bother logging a call as 'missed' in the case of another phone picking it up. I'm sure there's a way to hack this using the current functionality (or if not, a slight modification of current functionality), but if anyone's done it and has a code snippet, that would make life easier.
