The IP Phone 1110 and 1150E are not supported on SRG 50 Rls1.0.
Although not required, it is strongly recommended that SRG 50 1.0
customers upgrade to 2.0 to ensure the latest feature and software
application support across the IP Phone portfolio
SRG 50 2.0 Nortel recommends an upgrade to these firmware releases at the earliest
opportunity.
No SRG 50 patches are required to support the Enhanced Firmware
Download feature that allows the IP Phone firmware supported on the SRG
50 to remain in synch with the Communication Server 1000 Main office.
SRG50 2.0 officially extends support for the following set types:
IP Phone
2000 Series Key Expansion Module (KEM)* (in Normal Mode only),
IP
Phone 1120E, and IP Phone 1140E.
In addition, if the “Main” is Communication Server 1000 release 4.5, no patch
is necessary on the Communication Server 1000 to upgrade the IP Phone.
But if the “Main” is Communication Server 1000 release 3.0 or 4.0, a
Communication Server 1000 patch is required on the “Main” to allow the
SRG 50 to upgrade the IP Phone firmware. The patch is MPLR21148 and is
available from the Meridian PEP library at the
www.nortel.com/support web
site.
The IP Phone 1110 and 1150E are not officially supported on SRG 50 2.0
and is therefore supported in normal mode only.
