I have a client with an office using a few dozen GXP2130 phones plus a single GXP2140 phone. I set up multicast paging as per the document:
But it turns out I can’t have the initiating phone also listen to the same multicast address. When I do, it answers its own outbound page as if it were a concurrent inbound page. Ignoring the problem of the extra feedback caused with the speaker and earpieces being in such close proximity, for now. And then when done paging, I have to hang up twice: once for the answered-on-speakerphone call, and once again for the outbound page.
What this means is that we can’t set up ALL the phones to universally be both senders and recipients of multicast pages.
I see that a similar problem was posted back in 2014, with only a promised “future” fix. Is there at least a workaround? Something besides setting up multiple paging groups, because there’s more phones than available groups (a limit of 10).
