Hello I have a strange problem. I have the following network topology. I have 2 LAN networks that are connected via the Internet by IPsec tunnel. The problem is that IP phones that are in the network 192.168.70.0/24, from time to time do not want to connect with PBX 192.168.1.10.
There are ping to the PBX (192.168.1.10) from computers (192.168.70.10) that are networked 192.168.70.0/24 is OK. Problem correct only after changing the IP address of the IP phone.
For example: from 192.168.70.70 to 192.168.70.71
This occurs when, from IP phone has not spoken long time (there was no traffic)
What could be the problem?
