Intersite calls not working on UC560 - UC540 multisite

[graeme]

Hi there,

Setting up a UC560 Site1 and UC540 Site 2 Multisite setup.

Followed the Multisite Manager config, and the multisite status shows as up.

I can ping from Data VLAN on Site 1, 192.168.1.1 to data VLAN on Site 2 192.168.20.1

If I make a call from site 1 - 82300 the extension on site 2 rings with the rigth caller ID etc, but when answered nothing happens, and the extension on site 1 displays unkown number.

If I make a call from site 2 - 81273 the phone reports number unkown straght away.

Any one got any suggestions on where to start looking?

Thanks

Graeme
