Hi,
We setup small VoIP
gateway using Cisco 1750 & FXO Card. Here is the diagram
:
Cisco
1750 A (WAN Interface using Public IP) ------ LAN (Public IP)
|
|
Internet
|
|
Cisco 1750 B (WAN
Interface using Private IP) ------ LAN (Public IP)
From Cisco 1750 A,
we can make connection to Cisco 1750 B ... but after the phone ring, we can't
hear any sound (I suspect the RTP can't be sent to cisco 1750
A).
And from Cisco 1750
B can't make connection to Cisco 1750 A.
The VoIP
configuration is working well on the normal LAN (not using private
IP).
Is it because on the
Cisco 1750 B WAN site using PRIVATE IP (discontinous IP) address
?
regards,
Ibam
