Please try this programming which has proven to solve this issue.  This programming adds mute dialing and delays before and during the dialing of the digits (1 second):


***.    (wait for beep)  
**9**  (wait for beep)
*9*1**200*NUMBER**  (wait for beep)

**235* (enables off-hook dialing) (wait for beep)
**4*11* (inter digit timer settings) (wait for beep)

**2110* (wait for beep)
**2210* (wait for beep)


If there is still not fixed, try the next programming:

***       (wait for beep)
**9**   (wait for beep)
*9*1**200*NUMBER**  (wait for beep)
**27** (enables loud dialing tone) (wait for beep)
**235*    (wait for beep)
**4*11*   (wait for beep)

**2110*  (wait for beep)
**2210*  (wait for beep)


If time delays of 1 second is not long enough, you can use 1.5 seconds:

**2115*
**2215*

Or 2 seconds:

**2120*
**2220*


If you are programming it remotely (calling it from another line), then you must precede with the following command:
*#1234 (wait for beep)


If you wish not to hear it dialing, then enter this command:

**278* (enables mute dialing)  (wait for beep)
