Language Support - SIP telephones support the same languages as H.323 telephones, with
the exception of Hebrew. SIP does not support Hebrew or the English Large Text Font for any
language. Further, all SIP language files have .xml file extensions whereas H.323 language
files have .txt file extensions.
SNMP & MIBs - Although both SIP and H.323 telephones support SNMP v2c and have custom
Management Information Bases (MIBs), the MIBs are formatted somewhat differently.
RSVP & VMON (VMM) - 9600 Series SIP IP Telephones do not use RSVP (Resource
ReSerVation Protocol) software to provide real-time monitoring and historical data of audio
quality for VoIP calls. 9600 Series SIP IP Telephones do support Avaya Voice over IP (VoIP)
Monitoring Manager (VMON, now called VMM). 9600 Series IP Telephones use both RSVP and
VMON.
QoS - Unlike H.323 telephones, 9600 Series SIP IP Telephones do not use Avaya
Communication Manager to set Quality of Service (QoS). The SIP IP telephones use the
parameters L2QAUD, L2QSIG, DSCPAUD, and DSCPSIG (described in Table 11:
9600 Series
SIP IP Telephones Customizeable System Parameters).
NAT - 9600 Series SIP IP Telephones do not support Network Address Translation (NAT); 9600
Series IP (H.323) Telephones do support NAT.
