I am armed with CISCO891-K9 V01
There is a tunnel for voip:
ip address *REAL.IP* 255.255.255.252
ip mtu 1420
tunnel source FastEthernet8
tunnel mode ipsec ipv4
tunnel destination *REAL.IP*
tunnel protection ipsec profile voip
The provider gives a static IP, and this is how the Internet access is set up:
description <<< Outside >>>
ip address *MY.IP* 255.255.255.0
ip nat outside
ip nat inside source list 1 interface FastEthernet8 overload
ip nat inside source list NAT_outside interface FastEthernet8 overload
ip route 0.0.0.0.0.0.0 *PLUS_PROVIDER*
ip access-list extended NAT_outside
deny ip 192.168.0.0 0.0.0.255 10.0.0.0 0.0.0.255
permit ip 192.168.0.0 0.0.0.255 any
access-list 1 permit 192.168.0.0 0.0.0.255
Here's the question, the Internet works fine at 100mbps
But the telephony is glitchy, it doesn't ring, it resets...
I was told that I needed to add the MEDIA SERVER from SDP.
How to do it and what is it?
