t38
Enables support for the T.38 fax relay standard.
When you enable T.38 the system uses T.30 to transmit faxes as voice
(in-band) or T.38 to transmit faxes as separate packets (out-of-band)
according to the MGC's configuration.
C 13

Disables support for the T.38 fax relay standard. The system uses T.30
to transmit faxes as voice (in-band). C 13

Sets whether to use UDP or TCP as the H.248 transport protocol.
Default: tcp C 13

define settings for transmitting data in order to improve voice quality.
Whether or not V.152 is actually used depends on the MGC's
configuration. C 13
no vbd
Disables the Voice Band Data service. C 13
