DID Parameters.  The parameters applicable to the Direct Inward Dial 

(DID) telephony interface type are shown in the figure below and 

described in the table that follows.  The DID interface allows one phone 

line to direct incoming calls to any one of several extensions without a 

switchboard operator.  Of course, one DID line can handle only one call 

at a time.  The parameters described here pertain to the customer-

premises side of the DID connection (DID-DPO, dial-pulse originating);  

the network side of the DID connection (DID-DPT, dial-pulse 

terminating) is not supported. 

 
 

 

 

Interface 

DID-DPO 

Enables the customer-premises

 

side of DID functionality 

MultiVOIP’s use of DID applies 
only for incoming DID calls.  
The Start Mode used by the 
MultiVOIP must match that 
used by the originating 
telephony equipment, else DID 
calls cannot be completed. 

Start Modes  

Immediate Start, 
Wink Start, 
Delay Dial 

For Immediate Start, the voip 
detects the off-hook condition 
initiated by the telco central-
office call and becomes ready to 
receive dial digits immediately.
