>From the top of my head I can just change the validation mask for atxfer, now it always accept chars.
>From a standard phone is basically useless.
>From AMI works as expected.
>From a softphone (using my querty keyboard) I honestly didn't tried.

> {code:title=AMI command|borderStyle=solid}
> Action: Atxfer
> Channel: Agent/7001
> Context: atxfer
> Exten: a7002
> Priority: 1
> {code}
> in a telnet console, 'a' is filtered away from Exten resulting in a wrong transfer to '7002' and not 'a7002'.
