[cisco-voip] Berbee, multicast etc..

I believe Berbee tells ipphone to transmit to multicast address, then  
berbee server listens on that multicast address for the originating  
stream, then broadcasts that stream back out into the network.

take a packet capture at your originating phone.  Berbee does an HTTP  
POST of XML data to the ipphone telling it transmit.  the address  
will appear in the html payload of your packet capture.  make sure  
that address can route from your remote site to your central site.

I know there is a Berbee list, but I have a question..

If Berbee can send a page from a phone in the same subnet the Berbee
server is sitting in but can't send that page to a remote routed segment
when the Phone in the remote segment initiates the page.  What could the
cause be?

Situation 1:
	Phone IP a.b.c.200
	Berbee server a.b.c.102
	Phone initiates a page and it pages and live audio comes out on
phones on a routed Frame site on w.x.y.z /24 segment


Situation 2:
	Phone IP w.x.y.30
	Berbee Server a.b.c.102
	Phone initiates a page and all the berbee tones come out on the
speakers at w.x.y.z location.
		BUT live audio paging does not.

All routers are displaying the multicast route to the berbee server.

Ideas anyone?

Jim
