Hello All.
I had AVAYA 1692 H323 Conference Phone.
Unfortunately Avaya allows only H323 protocol for works.
As I understand Avaya 1692 is OEM of Polycom SoundStation IP 4000.
I want to connect AVAYA`s phone to Asterisk PBX via SIP protocol.
I was found SIP firware on support site:
https://support.polycom.com/content/support/north-america/usa/en/support/voice/soundstation-ip-series/soundstation-ip4000.html
My question is how can to upload new firmware (SIP) to Avaya 1692?
Do have someone an experience in this action?
Please help.
