polycom vvx phones to a pa system

[jmonroe]

We recently deployed a cloud voice solution through metaswitch, that uses polycom vvx 501 nad 350 phones. We have a customer who wants to page both all the phones and the overhead pa system. I have been able to find nothing to help me make this happen. anyone out there have any thoughts on this?

I believe you can do it if the overhead pa is a sip speaker.  It's then configured to be in the same paging group with the same multicast address and port.

Algo has sip speaker options. Very easy configure with poly phones.
