IAX and Realtime

Asterisk Asterisk Support
1

I’m trying to configure IAX for Asterisk Realtime, with MySQL ODBC.

res_odbc.conf

[asterisk_mysql]
enabled => yes
dsn => MySQL-asterisk
pre-connect => yes

extconfig.conf

[settings]
iaxusers => odbc,asterisk_mysql,iaxpeer
iaxpeers => odbc,asterisk_mysql,iaxpeer

Asterisk can connect to the database and retrieve data.

                         exten  _X.

                   sippeername  gnTel

When i start a SIP call that must be forwarded to the IAX trunk, the following is shown in the Asterisk debug console and i can’t start the call.

Sep 27 08:32:42 NOTICE[10678]: chan_iax2.c:6902 socket_read: Rejected connect attempt from 139..., who was trying to reach '070******@’

If I configure exactly the same in static configuration, it works good.
Maybe, Asterisk Realtime can’t query the database correctly?

I have found this bug report, but that is from more than 1.5 years ago.
