voice service voip
!--- Enters voice service configuration mode and specifies a voice encapsulation !--- type as VoIP encapsulation. Voice service configuration mode is used for !--- packet Telephony service commands that affect the gateway globally.
!--- Used to enable the H.323 voice service configuration commands.
h245 caps mode restricted
!--- The h245 caps mode restricted prevents Dual Tone Multifrequency (DTMF) !--- Named Telephone Events (NTEs) as well as T.38 capability indication in the !--- H.245 Terminal Capability Set packet. When these options are present, it !--- can prevent the H.245 negotiation from completing with some devices, !--- specifically with NetMeeting. Without the h245 caps mode restricted !--- command, calls in either direction will fail.
h245 tunnel disable
!--- By default, H.245 tunneling is enabled. This H.323 feature allows any H.245 !--- message to use the existing H.225 TCP session instead of bringing up a !--- second TCP session for H.245. Issue the h245 tunnel disable command to !--- disable this feature.
