[Asterisk-Users] Polycom Soundpoint IP400

[Elijah Hobbs]

I am trying to use a Polycom Soundpoint IP400 with my asterisk setup, 
and have been unable to find the proper firmware and application files 
to make it work.  The phone can access the FTP server, and downloads the 
IP500/600 configuration files, but claims that the sip.ld file is larger 
than its file system.

 I can think of two possible ways to make this work.

One is to find the IP400 firmware and configure the phone to use H.323.  
I have had no success with finding the firmware for this phone on the 
internet, and Polycom tech. support has been rather elusive, so if 
anyone could point me to the files I would be much abliged. 

The second method is to upgrade the file system on the IP400 and see if 
it will run the SIP application.  This would be prefferable, because 
this phone is intended to be a low cost proof of concept, and we will go 
to Sip phones once the concept has been proven to the right people.  I 
imagine that this would involve replaceing a non-volatile memory chip 
inside the phone with an equivalent chip of higher capacity.  The 
possibility of doing this depends heavily on the design of the phone 
(whether the memory size is hard coded into the OS, whether the memory 
is external to the processor, what type of processor is used, etc.)

There is also a possibility that I am barking up the wrong tree.  If I 
am, I would appreciate it if someone could guide me to the right tree.

Thanks in advance.
