SMPP bind problem and checking existing connection with SMSC

[vram...@gmail.com]

Hello,
Thanks for the reply.
I am facing one problem.
SMSC binding failure when i try to connect and bind to SMSC.
I am using the exact bind parameters provided by the SMSC vendor.
But the binding is failed.
I am not able to find out the error.
When i contacted the SMSC Vendor they say that a application is
already connected to the particular login(SysID) account.
Actually 1 month ago i tried and i think the java program connected
and binded to the SMSC.
Do you think that the connection and binding to SMSC which was
successful 1 month still exists today.
If it exists how can i disconnect and unbind from the SMSC,so that i
can bind again.
Could you please guide me.
Also could you please guide me how can i find if there is any problem
with the particular bind parameter and this is the program i am
using.
SMPP 3.4.

Thanks,
Vijay.

Hi,

May be possible.
But When ever your application stops the session is expired and SMSC
must closed the Session.
As SMSC doesn't have any valid session it must be closed via there
end.

There may be two cases :-
1. SMSC is not closing the invalid sessions. They have to do it.
2. Some one othere application is running which uses the same ID
provided to you.

I am looking for a professional who can setup a SMSC for me.
