 DTMF-relay cisco-rtp

!--- Action: Call is placed from the PSTN through maui-gwy-04 
!--- and terminated on an FXS port of maui-gwy-06 (called number: "81560") 
!--- Notes: 
!--- 1)On maui-gwy-04, the incoming call is received on the POTS dial-peer 1, 
!--- which is configured for DID. !--- 2)On maui-gwy-06, no inbound VoIP dial-peer is matched and default 
!--- dial-peer=0 is used. Therefore, the DTMF-relay cisco-rtp negotiation !--- fails.
