VOIP Issue Between MY and SG

















1) Main Problem is one way call ( MA can call to SG ) after switching replace MA DVX with MA TX


i)I think this issue is NAT because all IPPBX are behind the Firewall. We have VPN Tunnel between these two sites. It shouldn't be. My concept is wrong . It's totally wrong. It is coz of Routing. I need to add inbound route at MA IPPBX server. Wahhh So funny thing and confused Issues. I've been headache for that for about one month.

ii)I added some codecs at MA sites also so that they can call to DVX7090 and they will know eachother
