Thats why I made it configurable, so that it can be turned off, when not
needed. ;)

Your suggestions are reasonable if you know the dialplan. In my case it
can be possible that I will forward a number block to a customer. I have
not (and will not have) any knowledge of the length of the numbers the
customer uses, I only know the base of the block, neither does the
customer have to use an asterisk as termination.
Example:
I have a block +49-241-9909888 [0-99999]. I forward this block to a
customer. This customer can add one to five digits to this block
depending on his needs and I will never have knowledge of how many
digits he uses.
As you see, if you want use chan_ss7 as a multi-customer SS7-to-SIP
gateway with a national numbering plan without fixed length numbers (as
in the US) there is no way around a timer. It's sad but true. ;)

It works here without the answer as there is early-Media after receiving
an IAM. This works also with MOH instead of the ringback beeps, what can
be quite funny.
