Internal extension and external CELL phone - revisited

With Avi's help I have the dial string corrected to:
Dial an internal extension. Delay 10 seconds, then dial external number (which happens to be a cell phone)
The goal is to set the call timeout to keep the voicemail in FreeSwitch. (For this discussion let's ignore the variability of time to make a connection to a cell phone.)

After 10 second delay, FreeSwitch dials the external number just fine.  Then the external leg gets a
switch_core_media.c:8980 sofia/external/14108089999 Set 2833 dtmf receive payload to 101
It immediately hangs up the internal extension with a
switch_ivr_originate.c:3716 Hangup sofia/internal/220 at<mailto:sofia/internal/220 at> [CS_CONSUME_MEDIA] [LOSE_RACE]

Note, the cell phone never gets answered by the recipient. Sadly, the call does go to the cell voicemail.

Here are my questions:
1 - Is that because the Cell Carrier has actually "answered" the call and is now routing it to the phone?
2 - Can I even go to voicemail on FS after that event or is the call "answered"?
