[Serusers] 486 Busy & 2 UAs with identical usernames

[Ramin Nikaeen]

Friends,

 

I am using 2 SJPhone UAs (B, C) on two different networks, that register
with my SER server 

using the same (username=XXXXXXX, password).

 

 

                 >SJPhone - B (username:XXXXXXX)

               /

        INVITE

         /

SJPhone - A (username: YYYYYYY)

          \

          INVITE

                 \

                   >SJPhone - C (username: XXXXXXX)

 

 

 

I dial the phone number XXXXXXX from a third SJPhone (A). 

 

When only one of the destination SJPhones is registered with SER, 

let's say B,  then B rings. Then while B is ringing, if "ignore" button

is pushed, a 486 is generated by B and sent back to SER. Then 

SER receives the 486 in failure_route and processes it.

 

But when both B and C are online, both B and C ring. 

when "ignore" button is pressed on B, 486 is generated by B and

received by SER but SER does not enter the failure_route.

 

When ignore is pressed on the first destination, I expect SER to 

send a CANCEL to the second destination and receive the 486

generated by the first destination in the failure_route so that I 

can forward the first destination to voicemail!

 

Can anyone share any insight as to why this is happening?

 

Thank you for your help in advance
