[Asterisk-Users] 2 servers

[Altus Snyman]

Good day all
I've tried my iax conf and I'm struggling.So I want to know If someone
else got this working and if they can pleas send my their configs
I have to asterisk server,in different tows,both offices connected wit a
direct line so both servers are on the same network running SIP.Each
town got different extension register to each sever.Town A=100+ town
B=200+
How do I get town A people to dial 201 and it will go to sown B's
server's 201 SIP users
Please not that I'm only a newbie and my terms may be wrong but I'm
really having a bod time with this
Please help
Thanks
