# RTU answers incoming calls, but does not reach dialed number

RTU answers incoming calls, and also goes into alarm when it should, and attempts to dial out, but does not reach dialed number. First, verify whether the RTU is actually attempting to dial out, as evidenced by pulsed dialing clicks or tone dialing sounds, followed by message recital. If not, then see the separate problem below:

Unit does not go into alarm when it should:

1. Enter PROGRAM mode by pressing the PROGRAM key.
2. Read the present mode by pressing keycode 40 7 and the ENTER key.
3. Then set the operating mode by entering 40 7 *1 for TONE or 40 7 *0 for PULSE.
4. Then press NORMAL and repeat the manual DIALOUT procedure.
5. Verify that you have configured complete phone numbers including any area codes, or prefixes that might be required to complete the call.
6. Consider whether your phone system requires a prefix such as 9 to be dialed, followed by a delay period (to access an outside phone line) before dialing out. One-second delays can be added to phone strings by entering commas. Commas can be easily added to the dialing string with Alarmware™, or with a #5 when using keycodes.
7. You can also try temporarily connecting a regular telephone to the line normally connected to the RTU and see if you can successfully dial out to the same telephone number with that telephone. This would reveal whether there is a problem with the phone line, and whether the number the RTU is trying to dial is valid.
