This command creates and configures an H.248
profile.
h248-profile: This H.248 profile name (up to 31
characters).
mgc-ip, mgc2-ip: The IP address of the primary or
secondary media gateway controller.
mgc-dn, mgc2-dn: The domain name (up to 63
characters) of the primary or secondary media
gateway controller.
mgc-port, mgc2-por: This is a port number
(1025~65535) the primary or secondary media
gateway controller uses to send and receive H.248
packets.
transport udp|tcp: send H.248 packets to the
media gateway controller via User Datagram Protocol
or Transmission Control Protocol.
encode long|short: send H.248 packets to the
media gateway controller using long or short form
text encoding.
pbit: The IEEE 802.1p priority tag for H.248 and RTP
packets (0 ~ 7).
dscp: The DiffServ Code Point for H.248 and RTP
packets (0 ~ 63).
it: Set the inactivity timer (0~65535) in units of 10
milliseconds the IES-1248-51V waits for the MGC's
response before disconnecting the connection with
the MGC.
prefix: the ephemeral termination prefix, up to 31
characters. In H.248, each Terminiation has an
ephemeral termination ID during communication with
other terminations for identification purpose (see
Section 45.1.2 on page 318). For example, RTP/0.
The IES-1248-51V allows you to customize the prefix
string (“RTP/” in this example). You must configure
the same prefix string as the setting on the MGC.
softswitch DEFVAL|zxss10-ss: set this to zxss10-
ss if the IES-1248-51V's MGC is a ZTE ZXSS10
softswitch. Otherwise, set this to DEFVAL.
vbd off|on: disables or enables Voice Band Data
(VBD) support. See Section 45.1.8 on page 323 and
ITU-T V.152 for more information.
forcever off|on: uses h.248 version 2 (off) or
version 1 (on).
