atcomsystems.ca/forum Forums Other TDM Phone Systems Sprint - Tadiran Telephones & Systems SIP Terminal Grandstream HT-502 problem on IPXoffice

No, the box on different subnet.
I have two location connected through Site to Site Tunel (VPN).
On the remote location which has HT502, also has some T207M. Those T207M works fine with central office except the HT502 box. The HT502 box only works good between other ATA Box in central office.
I set trusted network for the tunnel.
Is there anything else that I missed?

Thanks
