I need to dial into a telephone bridge and then access a menu; can I enter extra digits via LQ after dialing the main number? 
A DTMF access code can be entered in sequence following the phone number being dialed.
At times the device requiring the DTMF access code will need a distinction between the phone number dialed and the DTMF access code.
For this purpose, as well as to be able to accommodate the intricacies of various situations, then a delay can be added into the sequence dialed.
The delay is added with a comma "," symbol where each comma adds 500ms of delay before proceeding to the next characters. Commas can be added to add delay.
Example for dialing Clear-Com's US Technical Support;
Normal dialing
+1 510 337 6600
Option 2
Option 2
When dialed in LQ using the LQ CCM (Web browser page) ; +15103376600,,,,2,,,,2  >> then hit the dial/off hook button
Note: This can be programmed into a speed dial if using EHX v9.1 or later firmware or manually dialed from a v-series panel
