A stupid old autodialer on win95 was to be ported on an ONS port on a 3300 MCD 5.0, and it needed to connect to a centrex line but could not dial 9 by itself on it, so a line sharing device like a fax switch could not be used.
1)x225 (dialer) associated hotline to SC300
2)SC300 dials 400
3)ARS digits dialed 400, 0 to follow, uses route 50
4)Route 50 uses a Trunk Group containing the centrex line, digit mod 5
5)Digit Mod 5 absorbs 3, inserts <T01>9 (T01 waits for initial dial tone outpulse default, then 9 connects to the centrex 2nd dial tone)
6)Dial tone gets returned to the autodialer which never sees the difference!!
