[Serusers] ser route config problem again - sr-users

26 Nov 2003


      sorry for again and again because my mail seems to be unreadable
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:
