[OpenSIPStack] OpenSBC upper registration feature

[<bay...@ic...>]

Dear All,

Right now, I am trying the opensbc upper registration feature. I have  
made the upper registration route to our SIP server (that could not  
handle SIP client behind NAT). The credentials are :


OpenSBC Mode :

Full Mode


Upper registration route :

[sip:8*@SIP.Server.IP.Address:5060] sip:DOMAIN.com:5060


Internal DNS Mapping :

[sip:DOMAIN.com] sip:SIP.Server.IP.Address:5060


By using above configuration, my SJ phone could be registered by using  
credentials :

Proxy domain = Open.SBC.IP.Address
User Domain = DOMAIN.com


Both the SJ Phone and OpenSBC Registration Status indicate that the  
SIP registration is successful.

But after dialing, the SJ phone status is "Creating Out Going Call"  
for some times then it drops with status "transaction status: time out".

I have tried to define the relay routes this way :

[sip:8*@SIP.Server.IP.Address] sip:SIP.Server.IP.Address:5060

and the result is exactly the same. and according to the tethereal  
output during the dialing, the logs state that there were only some  
SIP registration activities.

Please kindly provide me solution and advice about this problem.


Best Regards,


Bayu Sukmanto
