Answer Problems

Problem
Your modem does not auto-answer incoming calls.
Solutions
1. Make sure the supplied telephone cable is connected to your modem's LINE
jack and not the PHONE jack.
2. Your modem may not be set up for auto-answer. With the modem in
command state, type ATS0=1 and press Enter to have the modem answer on
the first incoming ring. To auto-answer on a different ring, replace 1 with a
value up to 255. Do not assign a value of 0, which turns off auto-answer,
unless your software can respond to the modem's RING result codes.)
3. Check that the DTR LED is ON, and that the AA LED flickers with each
incoming ring. If the LEDs do not respond in this way, refer to your ZyXEL
Modem Reference Manual.
Problem
When you receive a phone call, your modem immediately seizes control of the
telephone line.
Solution
Your modem may be configured for auto-answering. To disable auto-answer,
type ATS0=0 and press Enter with the modem in command state.
