[asterisk-users] Variable using AMI

[Carlos Ruiz Diaz]

I am sorry for my bad English. Apparently I'm explain myself wrongly but you
got the point.

I tried GetVar as AMI action but I have to specify a channel string. Of
course I have the channel string, I parametrized it but Asterisk adds
another string to the original channel and I can't obtain the variable value
because of the lack of the real channel string.

eg.
I write SIP/1000 in the channel param. but asterisk adds SIP/1000-*12eg12*.
Obviously is not always the same string. This is just a illustrative
demonstration.

I wrote a mail asking for help with that problem.

Thanks.
