I have connected my odbc to MSSQL server and I'm getting sip accounts and dialplan from that and I also can call between two peers but asterisk gets error :

  • I got same warning message on asterisk 13.3.2 (official package from http://packages.asterisk.org/centos/6/asterisk-13/x86_64/RPMS/). OS: CentOS 6.7 – LiuYan 刘研 Jan 28 '16 at 11:44

As clearly state in asterisk documentation you have option for escape charaster which is probably incorrect set in your config.

in sample config file:

; Is the backslash a native escape character?  The default is yes, but for
; MS SQL Server, the answer is no.
;backslash_is_escape => yes

  • If you changed that param and still not work, i think you should debug source code to see if this param work in your asterisk version or not. – arheops Jan 27 '16 at 18:40
  • Teach yourself c/c++ in 21 day and read asterisk source code. – arheops Jan 29 '16 at 01:26
  • What you expected on question "how to debug source code"? Sure you need know basic of programing for that – arheops Jan 30 '16 at 04:17
