[Users] determining if From==To
by Mark Price 15 Dec '06

15 Dec '06

Hi, How would one determine if the From address equals the To address, or even better, if the To address is either the same as or an alias of the From address? Thanks Mark Price

[Users] new MediaProxy release 1.8.0
by Adrian Georgescu 15 Dec '06

15 Dec '06

Hello, There is a new MediaProxy release available. To upgrade go to http://mediaproxy.ag-projects.com or download the software directly from: http://mediaproxy.ag-projects.com/mediaproxy-1.8.0.tar.gz Changes from version 1.7.2 to 1.8.0 ----------------------------------- - Added support for radius accounting. The accounting type can be specified in the configuration file. To support radius accounting the pyrad module must be installed (available at http://www.wiggy.net/code/pyrad/). - The old boolead switch dbaccounting in the [Accounting] section of mediaproxy.ini was replaced by accounting which is a string specifying the accounting type to be used: none, radius or database. For those using CDRTool, release 5.0 is available, which works with the new Radius accounting of MediaProxy 1.8.0. To upgrade go to http://cdrtool.ag-projects.com/ or download the software directly from: http://download.dns-hosting.info/CDRTool/cdrtool_5.0.tar.gz Kind regards, Adrian Georgescu

[Users] NEW FEATURE: new pseudo-variables from dialog module
by Bogdan-Andrei Iancu 15 Dec '06

15 Dec '06

Hi everybody, the dialog module exports 2 new pseudo variables: *DLG_lifetime* - the duration (in seconds) of the dialog. The duration is calculated from the dialog confirmation and the current moment. This PV will be available only for sequential requests, after doing loose_route(). So, it can be used to get timestamps foe sequential requests, or to get the overall dialog duration and to use it for accounting. Closes Feature Request 1611930. https://sourceforge.net/tracker/index.php?func=detail&aid=1611930&group_id=… *DLG_status* - Returns the status of the dialog. This PV will be available only for sequential requests, after doing loose_route(). Value may be: 3 - Confirmed by a final reply but no ACK received yet. 4 - Confirmed by a final reply and ACK received. 5 - Dialog ended. Can be used to delay re-INVITEs until ACK is received and avoid signalling races. Closes Feature Request 1610630. https://sourceforge.net/tracker/index.php?func=detail&aid=1610630&group_id=… regards, bogdan

[Serusers] Interdomain remote disconnect
by Maciej Żwirski 15 Dec '06

15 Dec '06

Hi, I've a following problem: I'm dialing over voip to another domain. Everything swings except that when a remote party hangs up, I don't get a disconnect signal at my caller. Instead I'm getting ". I'm pretty sure I messed up something with my force/unforce proxy but I just can't get it working right. Note that when I'm calling to the PSTN (same transit proxy) through Asterisk I do get the disconnect signal. Any help would be appreciated :). Below is the config of my local proxy. I can post my transit proxy conf if needed.

Hi Bogdan, I am not using any nat test functions, at least at the part of the script that handles INVITEs. I am using allow_trusted() in caching mode. But if allow_trusted was doing the DNS query then I should also see it after the first INVITE and before the "407 Proxy Auth Reqd". I am also using lcr module. So, is it possible that load_gws() or next_gw() is responsible for the DNS query?

[Serusers] transfer to a speeddial number
by jorain 15 Dec '06

Hi all, How to get the referred-by value from sip message header? I need it to transfer the call by dialing speeddial number which was stored in speeddial table. Because it will take the original caller (first caller) as the username instead of the second party who did the transfer. For example, speeddial table: ----------------------------------------------------------- username sd_number new_uri 55555555 123 55555550(a)205.5.5.5 33333333 123 33333330(a)205.5.5.5 When i call from 33333333 to 55555555, then 55555555 transfer the call to 123, by right it will call 55555550(a)205.5.5.5 , but now my system call 33333330(a)205.5.5.5 How can i solve it? Thanks. Regards, jorain
