Comment on Basic func_odbc starting point by epower

@Even: If a func_odbc read command doesn’t work, it’ll set the returned value to NULL. Use the ISNULL function to check if nothing was returned. For example, if a MySQL error was produced, there should be a log message and a NULL return value.

Is there ANY variable or ANYTHING else one can check to find the STATUS of the func_odbc command.i.e. if it FAILS or a mySQL ERRO was produced HOW can you tell ?

Comment on Cheating around ‘include’ in Asterisk realtime by Ish

You can include contexts to others in RealTime although you will need to learn some shell scripting

There is a file that is run every minute on the root crontab, on my setup it is

/usr/local/bin/db-ext.sh

this basically rewrites the extensions.conf and reloads the dial plan

It is in this file that you can add your own macros and get contexts to include other contexts

@Gaba: you’ll probably want an entry in res_obdc.conf like

[dinfw]
enabled => yes
dsn => …
username => …
password => …
pre-connect => yes

I would like to, but I'm no longer working in the TSSG so I no longer have access to the files. In any case they were rather cluttered with internal stuff. I haven't worked with Asterisk for almost 6 months so bear with me, but ill try to recall. IIRC, first of all you would have to configure func_odbc. Then add a func_odbc entry like so:


[GET_REGISTER_SERVER]
dsn=sipaccounts
read=select regserver from sipaccounts where name = '${SQL_ESC(${ARG1})}'

Then something like the following in extensions.conf


exten =>_XXX,1,Answer()
; somehow extract the name from the caller.. there was a function
; to do this... something like SIP_CHANINFO
exten => _XXXX,n,Set(regserver="${GET_REGISTER_SERVER(${name})})
exten => _XXXX,n,GotoIf($[ "${regserver}" != "" ]?${regserver},${EXTEN})
exten => _XXXX,n,Hangup()

Then you can add different contexts with the names of your various sip servers, as defined in asterisk.conf. Or, you could do a direct dial if the server names map to sip servers in a one-to-one fashion like so:


exten =>_XXX,1,Answer()
; somehow extract the name from the caller.. there was a function
; to do this... something like SIP_CHANINFO
; we store it in a channel variable called "name"
exten => _XXXX,n,Set(regserver="${ODBC_GET_REGISTER_SERVER(${name})})
exten => _XXXX,n,Dial(${regserver}/${EXTEN})
exten => _XXXX,n,Hangup()

It all depends on what kind of access control you need (we wanted some) and how your servers are set up. I recommend using a few virtual machines to setup a test bed before trying to do this on a real server.

Can you post the dial plan logic here? I would like to try it. Thanks

great! i receive an error:

Dec 28 22:33:06 ERROR[2429]: func_odbc.c:267 acf_odbc_read: No such DSN registered: dinfw (check res_odbc.conf)

so I’m still trying to understand res_odbc.conf
