• The PBX configures P2P group settings for each SIP trunk port, and P2P communication is only allowed
when both parties belong to the same P2P group.
• In an environment where P2P communication between IP extensions and IP trunks is not allowed due to
provider
restrictions, set IP Extension - SIP Trunk P2P to disable, or assign different P2P group settings
between callers.
Note
During
P2P communication, DTMF signals cannot be detected by the PBX since sound RTP packets are
processed directly between IP extensions and IP trunks. As a result, features that use DTMF detection
(e.g., DISA Call Transfer to Outside User) cannot be used. To use such features, change the settings to
allow for non-P2P calls, to create an environment where DTMF detection is available. Confirm with your
ITSP whether there are services which use DTMF detection and whether P2P communication is possible.
