Hi
I have build a sip environment
one pc A(red hat 9) as gateway , only enable NAT , and install
ser with nathelper
notebook B get ip from pc A , register to PC A's public
IP
notebook C is public and register SIP to pc A's public
IP
+-------------------+
|
PC C (Msn) |
+-------------------+
|
| Internet
|
+----------------------------------------+
| Gateway /
NAT
|
| Ser with
Nathelper
|
| PC
A
|
+----------------------------------------+
|
| Intranet
|
+-------------------------------------+
|
PC B (Kphone
3.14)
|
+-------------------------------------+
B call C , then C pick up the call , but voice from B to C can work ,
C's voice can't make it
My question is Nathelper this module is now only for Cisco is Sip ... ? and
is this module need
STUN server ?
Now , for ser , how to solve NAT/Firewall 's problem ? or it's
service provider's issue ?
Thanks
