i'm not sure if i get u correctly but if u mean to connect nowsms gateway to another smpp server then from smsc tab u select (add) then u select (smpp over tcp) and there u have every thing to configure including ur remote smpp server name and ip address and port number.
after that it's now sms descission to decide which port to send smpp commands to the target server. i've never seen any documentation for that, i only knew that nowsms uses port 8800 for recieving http requests.
i hope that helps!

Hi George,

We have support for that type of setting on UCP/EMI connections.

But I haven't seen this as a requirement for any SMPP providers.

You could only do this in an SMPP environment if you were binding with a single connection (transmitter only, or transceiver).

If your service provider requires this, we could add a facility for this setting. (It would take about a week to get it implemented.)

Thx for all..
i know it is rare to need to specifiy the SMPP local port but our provider requires that for the billing process
our connection with it is single connection
so we satisfy the conditions
if u know a programming library that uses a method with local port in the parameters passed to it
we can implement the porgram
if not plz tell me what shall we do
sincerely

Hi George,

I sent you an e-mail with an update that allows fixed ports to be specified for SMPP connections.

One thing to watch out for ... when you used fixed ports, after a connection is ended, it may take 1 to 2 minutes before a new connection can be established. So you may see some connection errors during this time period.

That is a limitation of TCP/IP. When a connection is established between 2 particular IP address/ports, after the connection is closed, TCP/IP won't let a new connection be established until after a timeout elapses. This is so any lost packets from the previous session don't confuse the new session.

We run into this with UCP/EMI when fixed ports are used. Basically, it's just a minor nuisance when you are making configuration changes. If you get a connection error, just wait a couple of minutes for the TCP timeout to elapse.

George,

v5.50 is a free update for v5.0 customers.

You should install v5.50 over top of v5.0 before applying the patch (as the patch only has components updated after the v5.50 release).

Programatically, you use the bind command to bind to a specific port.

Yes, there is a bind method associated with the Socket class in Java.

I'm not an expert in using it, but I can see from the docs that it does exist.
