Updating Polycom SIP Phone firmware

Polycom LogoThis process can be used on any of the Polycom SIP Phones which support 4.x software today (SoundPoint IP, SoundStation IP, VVX, and SpectraLink models).

This only applies to devices which are already running at least version 4.0.0 of the UCS firmware. In previous versions (Polycom SIP software 3.x or earlier) this manual process was not available.  Also the firmware was packaged differently in the previous SIP versions as the device firmware was provided as two separate binary files, the bootloader image and the application image.  In the 4.x UCS release these were merged into the same binary file.  New devices like the VVX500 and SpectraLink phones have only ever shipped with 4.x UCS releases, while older devices like SoundPoint IP phones may still have previous 3.x SIP releases on them.  In order to utilize Lync integration a one-time update process must first be used to upgrade devices running 3.x to 4.x.

Use a Mobile Phone as a GSM Gateway in Asterisk (Asterisk + chan_mobile)

Asterisk + chan_mobileMy task is to use mobile phone as GSM Gateway to my Asterisk with a help of chan_mobile so in case I’m unavailable on mobile people can leave a message in my voicemail box. SMS text messages arrive as emails, my replies to which are sent by SMS.
So I used my old Sony Ericsson k530i phone in pair with Asterisk by connecting it to ID 1131:1001 Integrated System Solution Corp. KY-BT100 Bluetooth Adapter USB dongle.

Asterisk support for bluetooth connections to mobile phones and headsets is accomplished through chan_mobile. Not all phones are supported, so it’s worth taking a look at’s page which lists the confirmed compatible dongles and phones. I am getting good results with a KY-BT100 dongle and Sony Ericsson k530i phone, Samsung Galaxy S4 phone.

Here is how to connect your mobile phone to Asterisk with chan_mobileContinue reading
