I configured an MX64 with a site-to-site VPN connection. I'm able to ping my call manager from the MX but the Cisco Phone that I'm trying to setup is not registering to the Call Manager (Cisco Phone Model 8865)
I also check the DHCP configuration and it looks good.
The weirdest thing is that I have another Network with the same model of MX and same site-to-site VPN connectivity and same Call Manager but different model of phone (Cisco 8945) and is working fine.
Both Networks and phones are located in Israel
What other thing can I check?
