Polycom Push-to-Talk (PTT)
**Please note - this article is for informational purposes only. This is not a standard feature of the OnSIP Hosted PBX and is unsupported. You are welcome to use the following information to enhance your OnSIP experience, but technical support is not available from Junction Networks for this feature. For assistance beyond the below document you will need to contact the hardware manufacturer/reseller directly.
Starting with version 4.0 of the Polycom SIP software, you can easily enable PTT (push to talk) directly through the Polycom phones. This feature is only available between phones on the same physical local area network and requires multicast. As stated above, OnSIP cannot help to support or troubleshoot this feature, but the below information should work on most networks without additional setup.
Step 1 - Gather IP Address
To enable PTT, you need to log into the WWW interface of the phones. To do that, simply obtain the IP address of the phone by choosing:
1. TCP/IP Parameters...
Step 2 - Configure PTT Channels
Take the IP address listed there and put it into the address bar of your browser. This will tak you to the web user interface for the phone. Log in with the admin username and password:
username: Polycom (Be sure to use capital "P"!)
From the "Settings" menu choose "Paging/PTT Configuration".
Choose the plus sign "+" next to PTT Mode Configuration to expand that section.
Choose "Enable" for PTT Mode.
Give the Default Channel a label identifying the user. Make the Available, Send and Subscribe categories all "yes".
Choose "Save" at the bottom of the screen and respond with "yes" to save the settings to the phone.
Your phone will now show a softkey for "Talk".
Step 3 - Repeat
Repeat these steps for all the phones on the network, or at least those phones you want to be PTT enabled. PTT should be set between two users so that there are only two phones per channel. For group paging, use the Paging feature.
Step 4 - Usage
To PTT another user, simply hit the "Talk" softkey on your phone and choose a channel. Then press and hold the "Talk" key. The phone will beep and you can then start talking. The non-busy phone will answer the call in speaker-phone mode.
