[Asterisk-Users] Polycom Soundpoint IP400

[mattf]

Hello,

As far as I've heard the IP400 doesn't have enough physical memory to store
all of the files necessary to run SIP. For those familiar with SIP, H323 and
MGCP protocols, SIP files are huge while MGCP takes up very little space and
H323 is in the middle. The IP400 phones were designed for MGCP protocol but
can supposedly run older H323 firmware as well.

Right now we only have support from Polycom for the IP500 and IP600 phones
running the SIP protocol. We are working towards getting support for the
MGCP and H323 products, but there is a lot more demand for SIP functionality
in the Polycom-Asterisk crowd than there is for either MGCP or H323.

I would recommend against taking apart your IP400, the memory is not easily
replaced, and there is no guarantee that it will work if you do manage to
solder it in correctly.

Try buying an IP500 or getting one on loan from a vendor for your test. I
can assure you that they work wonderfully with Asterisk and we are getting
more support from Polycom Corporate every month.

Subject: [Asterisk-Users] Polycom Soundpoint IP400


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.
