Polycom IP 7000 Speed Dial (Insert Pause?)

It used to be possible with a comma but I believe it needs to be done now with the sip.cfg to add a soft key.

Configuration File Changes
You must make the the following changes to the <feature/> parameter that is defined in the sip.cfg configuration file:
<feature feature.18.name="enhanced-feature-keys"
feature.18.enabled="1"/>

Action String Example
The action string
“$Changup$*444*$P1N4$$Tinvite$$Cwaitconnect$$P2N3$$Cpause2$$Tdtmf$$Changup$” is executed as follows:
1. The user is prompted for 4 digits. For example, “1234”.
2. The user is prompted for 3 digits. For example, “567”.
3. The user’s active call is disconnected.
4. The string “*444*1234” is sent using the INVITE method.
5. Once connected, there is a 2 second pause, and then the string “567” is
sent using DTMF dialing on the active call.
6. The active call is disconnected.

Speed Dial Example
Your organization voice mail system is accessible through 7700 and your voice
mail password is 2154. You could use a speed dial key to access your voice
mail if you entered “7700$Cpause3$2154” as the contact number.
