RE: [Serusers] lookup 2 uri - sr-users

3 Aug 2005

Just one remark: only one of the two URI will be translated to the contact.

I'll try to explain...

imagine the incoming Req-URI is 1001(a)test.com. When it passes the first lookup,
            lookup("aliases");
SER will retrieve the two aliases and put one of them as the new req-uri and the other as
branch.
  Req-URI: 1002(a)test.com  
  branch: 1003(a)test.com 
Doing the second lookup,
            lookup("location");
will put the contact of 1002(a)test.com as Req-URI (if more than one contact is present, the
subsequent bindings will be added as branches) and the 1003(a)test.com will be left as
branch untouched.
  Req-URI:  1002(a)10.1.1.102 
  branch: 1003(a)test.com
This happens because lookup() only takes as input the req-URI.

The result is that SER makes a DNS query for test.com, to send the request to
1003(a)test.com, instead of the end-point. If the DNS is properly configured, test.com
should point to SER itself, making SER sending the message to itself via the network.
Depending on the config file, it can work but you should check the logs to see what is
exactly happening.
User 1002 will get the message without any problem.

NOTE: depending on the order in the database, 1003 and 1002 can exchange roles in upper
explanation.

As SER is now coded, above can not be changed (as far as I know)....

Hope it helps,

Samuel.

 Hi Atle,

 Alias doesn't replace uri with its real location. I'd like to use
 lookup("location") to find out its real location. For 
 example, if 102(a)test.com is at 102(a)10.1.1.102 and 
 103(a)test.com is at 103(a)10.1.1.103. I'd like to replace all 
 uris with 102(a)10.1.1.102 and 103(a)10.1.1.103 in a single ser 
 transaction  logic. Would it be possible?

 Thanks,
 Richard

 Hi,

 you could do something like :

 serctl alias add 101 sip:102@test.com 
 serctl alias add 101 sip:103@test.com 

 This way the invite would be forked to both 102 and 103,

 just remember to have both lookup("aliases"); and  
save("aliases"); in 
  your config at the right spot :-)
