[asterisk-users] Polycom - how to 'buddy watch' trunks?

[Robert Jenkins]

Hi,

I've recently got some Polycom 501 & 601 phones.
I have buddy watch working & showing the status of users listed in the
directory.

I would like to also have the status of the trunks (ZAP via TDM2400E & SIP)
on the IP601 Sidecar display, but I cannot so far find any info on this? 

Thanks,
Robert.
