[Serusers] unconditional forwarding cpl script

[Richard]

Hi Bogdan,

Thanks for your help. I removed the t_newtran. It
works now. What is the best approach to run cpl
script? I found the original segment of ser.cfg script
from the archieve. But I can't find it now...

You are right. It is call redirect.

Thanks,
Richard
