[asterisk-biz] asterisk redirect to PSTN

[sunxiujun26 at sina.com]

hello everyone, 
I have two asterisk pbx , server A with a WAN IP,and server B with a LAN IP. 

Server B connect to Service Provider through a E1 trunk and users at server B can make PSTN calls.I want users at server A can do this too. 

for example,user1000 @ server A, user2000 @server B. Now user2000 can communicate with PSTN , and I want user1000 can communicate with PSTN numbers through server B. 


Can asterisk do this ? 

How can I achieve it ? 


things I have done: 

1. add a peer in sip.conf on server B: 

[serverA_siptrunk] 

type=friend 

host=serverA's IP 


2. add a peer in sip.conf on server A: 

[serverB_siptrunk] 

type=friend 

host=serverB's IP 


3. config the outband to serverB_siptrunk on server A 


result: 

user1000 at serverA call a PSTN number 1234567, serverB receive the invite number , then return 603 delinde. 

I don't know what's wrong,and I hope someone can give me some advice . 



Thank you in advance! 


Best wishes!
