Prefix Service

The Edit Simplified ISDN Gateway Dialing Prefix dialog lets you edit a prefix-driven simplified ISDN 
gateway dialing service. 

The following table describes the fields in the dialog. 

Available ISDN gateways 

Lists the ISDN gateways that have at least one session profile specifying an 
H.320 or PSTN protocol. See 

Selected ISDN gateways 

Lists the selected ISDN gateways. The arrow buttons move gateways from 
one list to the other. 

Note: ISDN gateway vs. H.323<->SIP gateway
This feature is not related to the Polycom RealPresence DMA system’s built-in H.323<->SIP gateway. 
Simplified ISDN gateway dialing is for routing calls to H.320 or PSTN protocol gateways. 
This feature isn’t supported for calls from SIP endpoints, but SIP endpoints can make ISDN gateway 
calls by directly calling an MCU/gateway using its direct dial-in prefix (see

Simplified ISDN dialing prefix

The dial string prefix(es) assigned to this service.

separated by commas (44,46), or a combination (41, 44-47, 49). 
If your dial plan uses the Dial services by prefix dial rule (in the default dial 
plan) to route calls to services, all dial strings beginning with an assigned 
prefix are forwarded to this service for resolution.
