[Serusers] checking permissions with if (!$f.gw_acl=="1")

by Davor Jovanovic

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

Re: [OpenSER-Users] FW: OpenSER 1.3.2-tls - error tcp_blocking_connect

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

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
