[arm-allstar] suppressing telemetry to SIP clients

[Rob Seaman]

Hi Patrick,

I had the same issue with Cisco SPA504 desk/hard phones beeping away every 15 seconds with all the nodes connected.  It took a while, but finally solved it turning off some message waiting setting.  Possibly the softphone has something similar?

Regards,

Rob...
