Trixbox with PIX VPN. Remote phone can call but not receive calls
I've searched a great deal but haven't yes been able to find an answer that solves my problem.
In the main office I have a PIX 515e with static IP. In the remote office I have a PIX 501. I'm using cisco 7940/7960 phones.
I edited the sip_nat.conf file by adding the following:
localnet=10.3.3.0/255.255.255.0 # VPN1 to 10.1.1.0
localnet=10.4.4.0/255.255.255.0 # VPN2 to 10.1.1.0
I also disabled the sip fixup protocols on both PIXs:
no fixup protocol sip 5060
no fixup protocol sip udp 5060
The remote phone can call any extension of a phone in the main office and the call works perfectly. I notice that trixbox doesn't show the remote phone as connected though and also phones in the main office cannot dial the remote extension. I'm thinking its a firewall configuration but am not sure. Any help would be greatly appreciated.
