It turned out, that there is a  third provider in between, which doesn't
support T.38 ... .

Re: [asterisk-users] AGICommand_exec remove my double quotation

2017-05-03 Thread Lợi Đặng 
sr guys, but I found it out, commands like SET VARIABLE also have the same
problem, strip off my quotations.
solution is to escape the quotation with double slash \\.

*EXEC CELGenUserEvent DIAL_DATA,abc\\"xyz.*
It has been noted in res_agi.c

[asterisk-users] AGICommand_exec remove my double quotation

2017-05-03 Thread Lợi Đặng 
Good day, guys
As the subject, I'm sending this command for executing CELGenUserEvent via
AGI
*EXEC CELGenUserEvent DIAL_DATA,abc"xyz*
in asterisk cli with agi debug mode, I see that I successfully sent my
param *abc"xyz *to asterisk, but it removes my double quotation in
collecting the options to execute
cli:

*AGI Rx << EXEC CELGenUserEvent
DIAL_DATA,abc"xyz-- AGI Script Executing Application: (CELGenUserEvent)
Options: (DIAL_DATA,abcxyz)*

It leads to wrong data generated.
I tried other commands like *SET VARIABLE, *but my quotations don't get
removed. Single quotations are not removed in AGICommand_exec as well.

I'm not sure what I missed, helps are appreciated.
rgds,
Loi Dang
