[OpenSIPS-Users] 405 from UAS to UAC

[Nick Khamis]

Hello Everyone,


I am having a hard time registering a Polycom IP301:

* 192.168.2.11 is Poly
* 192.168.2.102 is OpenSIPS
* 192.168.2.103 is Asterisk
* 192.168.2.104 is Asterisk

 The following is my ngrep:

U 192.168.2.11:5060 -> 192.168.2.102:5060

Not quite sure why OpenSIPS is sending a REGISTER to the phone. I
know! Wrong configuration? ;)
The idea is to put a load balancing proxy, that is also in-charge of
REGSITER, between the asterisk
boxes and the clients. The entries I have in databaes are:

insert into domain value(0,'test.com',now());
insert into subscriber
values(0,'1001','astcluster.test.com','pass','mpeer at test.com','pass','pass',null);
insert into load_balancer
values(0,1,'sip:192.168.2.103','transc=200',0,'Asterisk One');
insert into load_balancer
values(0,2,'sip:192.168.2.104','transc=200',0,'Asterisk Two');


A sligehtly off topic, I am under the impression that "transc=200",
tells our BEAUTIFUL sip proxy
that only 200 SIP calls will be sent to the media servers?

The configuration file is mostly default. I could post it if requred

Thanks in Advance,

Nick.
