VOL.2-1632
MG-SIP96
Note:
The conditions of this command are as follows.
• This command is available for SP-3987 MGSIP PROG-B Issue 3 or later.
• In the Telephony Server side, a system data setting (ASYDL, System Data 1, Index 1144, Bit 6=1 (Codec
Change function is in service) is required to enable this function.
• In the Telephony Server side, payload type and payload size need to be assigned by AIVCL/AIVCN, AMGVL/
AMGVN, and ARTI/ARTIN commands.
• Also specify G.711 (fixed) as FXPT (Payload Type for IP FAX) and specify the payload size equal to that of
voice data as FXPS (Payload Size for IP FAX). Then assign the FXPT and FXPS data to AIVCL/AIVCN and
AMGVL/AMGVN commands.
• Payload size cannot be converted in MG-SIP96. When an RTP packet whose payload size is 20 ms is re-
ceived from the Telephony Server network, the packet is transferred to the SIP network without converting
the payload size. Same behavior applies to the RTP packet received from the SIP network.
• To use the following methods, enable commands shown below.
- [ReINVITE] method: enable “set sip_tel_service” command
- [UPDATE] method: enable “set sip_tel_service” and “set update” commands
