Question about Polycom CX300

Open Question

During a call, party on other end cannot hear me for a brief time.

I work for a major corporation and several of us in our office use the Polycom CX300 through Microsoft Lync 2010. We all also telecommute from home as well (via VPN), and the same issue happens at home as well as in the office. After a few minutes on the phone with someone they will not be able to hear us for about 5 seconds. Lately it has been every single call. We had someone who installed the phones come check and he has no idea. Can anyone make a suggestion on what we can do or what needs to be done?

Dear Sir/Madam,

1) After rebooting you can watch your ftp server and see the phone logging in and logging out. Its doing several things (checking the size of the bootrom.ld and sip.ld files and seeing if an update is necessary, etc etc) that I will go over later. It will reboot a couple of times to finish off the update.

2) After the reboots, lets be absolutely sure and lets check the bootrom and SIP versions.

  • Press the Menu button, 2 Status, 1 Platform, 1 Phone. Arrow down to view the BootRom version here.
  • Press the Menu button, 2 Status, 1 Platform, 2 Application, 1 Main. You will be able to view the "Version" number here.

If you did everything right, you should see the latest versions of the bootrom and SIP app that you had placed on your ftp site.

Now check your FTP site. You will notice that there are files being uploaded to your directory with *.log extensions. You guess it, these are just logs that the Phone dumps so you can trouble shoot when need be. If everything was done right, your phone will of seen the new bootrom.ld file and downloaded it, rebooted, and installed it. Next it will download your new sip.ld file and use it.

Ohh this mean, you did not register this extension on your phone system. Create this extension on your phone system. Be sure that password given on Phonesystem is also configured on phone too.

SOURCE: How do I set up my voice mail on my Polycom IP 330 Phone?

Voice mail is probably a feature provided by your service provider.
I have a PBX with several different viop phones configured.

The voice mail is stored on the PBX you just need to configure the message waiting light on the phone and possibly a speed button that automatically dials the voice mail code.

I assume that you don't have a PBX and an internet service provider / voice service provider has those features available for you. They should have the documentation you need to configure the phone. If they specifically support your model phone you are in luck. Otherwise you will have to adapt from their generic description.

I have noticed that some really cheap voice plans don't include voice mail.


Hope this helps.

As you have probably found, SIP phones are not supported until R5, which just came out.

It is not your T1. The T1 only controls the internet, not your local LAN. How old is the phone? It could be a bad phone....What system is it installed on?

Why does our office Polycom system go dark when no one moves?


There could be an automatic timeout when no movement is detected. The solution is to have everyone keep moving, even breaking into a lively dance from time to time.

After a brief power outage during a thunderstorm my canon i9900 will not turn on. I left it un pluged for several hours and then repluged it and still nothing. Everything else in the office works fine.


The power supply of your printer are damage due to the brief power output during the thunderstorm. Just check the fuse inside of the power supply of the printer if they have some burned or else use the Multi Tester to identify that the fuse are damage or needed for replacement.

Conference call with a Polycom SoundStation EX


The conferencing capability to bridge 2 (or more) external stations comes from the telephone equipment/service that you have purchased. Either you are behind a PABX or Electronic KSU, which provides multiple phone service to your office, or you purchase conferencing capability from your local telephone provider (Verizon, AT&T, etc). In either case, the way to initiate a conference call would be the same as when you would have a desktop/office phone and establish a conference/bridged call to external parties. Usually this occurs by having one party on the line, flashing the disconnect button momentarily, getting a new dial tone, dialing and connecting to a second party, then flashing the disconnect button again, which signals the equipment to bridge those two calls to your station.  On the SoundStation EX there is a Flash button that provides that capability of momentarily flashing the disconnect button.  Try and see if that works. If not, then you will need to make arrangements to purchase the external equipment or service from your provider.  If you have the PABX or electronic KSU, it may also be a configuration option that you will need to have your support person for your telephone system, activate for that station connected to the SoundStation EX. Hope that helps.
