Imperium1,
Setting up a House Phone is usually pretty straight forward and to this day I haven't had any problems with one working when I have verified the following.
Under System > Devices and Feature Codes > Phones > 11021
1. Associated Extensions > Outgoing Extension > 92000 [or whatever your ARS Feature Code is]
2. Class of Service > Day & Night > Verfiy that nothing is set to block the call types this 11021 will need to call
3. Flags > Set the following flags to Yes and all others to No: Camp-On to ARS, Extended Ring Cadence, Ring Intercom Always, Standard Tone Frequencies, Keep Redial Mode: Dialed, and Hunt Group can stay Replace
4. Verify Account Code Type is set to None
5. Set House Phone to Yes
6. Set House Phone Day & Night to 8 [or whatever your Outgoing Feature Code is]
7. Set Calling Party Number to a valid number on the PRI
Under System > Devices and Feature Codes > CO Trunk Groups > PRI Trunk Group
1. Verify that 11021 has Outgoing Access Day & Night
Now, hook your Test Set to the 11021 with the speaker on go off hook and dial your cell or test number slowly and see if the call goes out. If it stops and starts giving beeps then you need to write down the numbers you put in and determine why it is stopping at that point.
Thanks,
TE
