Hello,
I can see that you can use a smc firmware in the Siemens SX541, see the following topic:
http://www.ip-phone-forum.de/forum/viewtopic.php?t=21795&sid=672fbcf00d2deb46684f07a3bba9a220
That topic is based on the 1.09 firmware with booloader 0.67.3
And now SMC has a new firmware (2.04) with a new bootloader (0.69d)!! see:
ftp://dl.solcon.nl/pub/dsl/firmware/SIP/
BOOTLOADER-iad-boot_v0.69d.0 <-- bootloader
FW-ANALOOG-ARV4518HW-A-17-FW2_04_p.bin <-- the firmware for POTS
FW-ISDN-ARV4518HW-B-17-FW2_04_9.bin <-- the firmware for ISDN
First you must upgrade the bootloader and after that the new firmware.
I don't have the Siemens SX541, but I just share this info.
Like to see some comments of you if it works
