[Freeswitch-users] change event value

[Eli Hayun]

Hi
Is there is a way to intercept an event (for example : REGISTER) and
change one of its parameters (for example: the extension number) and
fire up the corrected event?

I need it to set the speedial of the phone value to be "**xxxxx" but to
make it register as "xxxxx"

Thanks
Eli
