Does anyone know if it’s possible to interconnect two ucm6510’s over an exciting VPN tunnel and use a single pri from one end for incoming and outgoing calls.
Site is configured as follows
Site 1 ucm6510 1 full 24 channel pri
Site 2 ucm6510 no pri but connectivity to site 1 over VPN.
Anyone have some guidance if this is possible without any additional hardware being bought.?
