Pls help me to config ser.cfg Now my envirmonet is: ser server: 172.16.255.1:5060 ( without DNS server ) SIP PSTN gateway: 172.16.255.1:6050 SIP UA: 172.16.2.xx And all SIP UAs have a PSTN number like 6169xxxx
There are no DNS server in the system.(we don't apply for a domain name) I want: 1 All users use digest authorization when SIP UA registing ------ finished 2 All calls from SIP UA need authorization (return 407 to Invite request) 3 All calls to PSTN transfer to the SIP PSTN gateway(number no like "6169xxxx") -------- almost finished 3 All calls from the SIP PSTN gateway do not need authorization(I think use a caller sip:gateway@172.16.255.1:6050 as caller when call from gateway,then all call from this user and this ip address needn't authorazation) 4 All calls need write CDR record to mysq datebase The bigest problem is I don't know how to write conditonal sentence , like if(uri!=~"xxxx") or if((uri=="xxxx") | (uri=="yyyy")) There are no document talking about the syntax.
Please help me. Any help is appreciate.
Now my ser.cfg is:

# we record-route all messages -- to make sure that # subsequent messages will go through our proxy; that's # particularly good if upstream and downstream entities # use different transport protocol record_route(); # loose-route processing if (loose_route()) { t_relay(); break; };
