[OpenSER-Users] Contacts in 3xx message on one line or multiple lines?
by Hiers, David 14 Jul '08

14 Jul '08

Hi, Openser seems to be happy with multiple contacts on one line in a 302 message. Contact:<sip:5551234567@255.16.250.13:5060;user=phone>;q=0.5,<sip:555123 4567@255.16.250.10:5060;user=phone>;q=0.25 If the leftmost contact is down, the rightmost contact is tried as expected. However, Openser does not like multiple lines of one contact per line: Contact: <sip:5551234567@255.16.250.16:5060;dtg=SIP-NS> Contact: <sip:5551234567@255.16.250.19:5060;dtg=SIP-NS> Openser uses the topmost contact and ignores the bottommost contact in the multiple line list. If the topmost contact is down, the bottommost is never tried. Is Openser supposed to be able to handle multiline contact lists? If so, what are the common configuration issues that we can expect to see?

[Serusers] checking permissions with if (!$f.gw_acl=="1")
by Davor Jovanovic 14 Jul '08

14 Jul '08

Hi all, I'm using SER2.0 (testing) and I have a question regarding checking the acl AVP to verify that the user is allowed to call PSTN destinations with if (!$f.gw_acl=="1") { ... In the "user_attrs" table I have this entry: uid name value type flags alice(a)xyz.hr gw_acl 1 2 61 before checking this "gw_acl" I do load attributes with load_attrs("$fu", "$fu.uid"); but I keep entering above "if" statement. So I would appreciate any help about how to solve this issue, in which tables I need to enter which values... I have solved this checking with avpops module and "avp_check" function, but as I already use new AVP schema in SER2.0 for loading other user attributes I would like to use it with this "gw_acl" also. Thanks /davor

TLS uses a different port than TCP. TCP is 5060 and TLS is 5061.

Hi, I've installed asterisk on a computer and openser on an other, I already have a mysql database for openser, and I'm now trying to install one for asterisk, but when I type: CREATE DATABASE asterisk; USE asterisk; CREATE VIEW voicemail AS SELECT phplib_id as uniqueid, username as customer_id, 'default' as context, username as mailbox, vmail_password as password, CONCAT(first_name,' ',last_name) as fullname, email_address as email, NULL as pager, datetime_created as stamp FROM openser.subscriber WHERE vmail = TRUE; I have the following error: ERROR 1054 (42S22): Unknown column 'phplib_id' in 'field list' I already had this problem for opensertcl, but I fixed it by adding WEBSER="yes" on openserctlr. thanks, Eliass

[OpenSER-Users] T.38 and RTP Read too short
by Jens Carl 14 Jul '08

14 Jul '08

Hey everybody, I use OpenSER (openser 1.3.2-tls (x86_64/linux), svnrevision: 2:4420) and the RTPproxy (1.1) and everything works fine expect for one thing. If I try to use T.38 with following scenario: SIP-FAX1 (NAT) <-> RTPProxy+OpenSER <-> Asterisk <-> Carrier the Asterisk always produce this kind of warning: 'WARNING[1493]: rtp.c:1145 ast_rtp_read: RTP Read too short'. The SIP-signaling with the re-INVITE works fine. If I get an re-INVITE I call the force_rpt_proxy( 'l' ). Has anybody an idea what I should change in the RTPproxy to get this scenario working? Thanks for your help, Jens
