Hello, I need your help to solve problem on SMSC connection. I have tried to make connection to a SMSC by SMPP over TCP/IP using NOWSMS/MMS Gateway. But right after I click on OK button for starting connection, there is an error notice on the screen: Unable to connect to SMPP server with specified parameters. ERROR: Bind Failed. When I make SMSC connection with the same parameters by using other gateway, the connection is OK. Please let me know what problem is and how to solve this problem. Thank you very much! | |||

Hi, The "ERROR: Bind Failed" response indicates that we are definitely connecting to an SMPP server, however the server is rejecting the login ... probably because a parameter required by the provider is not present. It could be an issue with the username (system_id in SMPP terminology) or password. Or it could be an issue with one of the optional parameters that the provider is requiring, such as "Address Range" or "System Type". There may also be an issue as to whether NowSMS connects as a transmitter and receiver or transceiver. The default behaviour for NowSMS is to connect as transmitter, with a second receiver connection if "Receive SMS Messages" is checked. If you want to connect instead as a "Transceiver", check the "Send and Receive Messages over the same connection (SMPP Transceiver)" box on the "Advanced Settings" page of the configuration. A less frequent issue may be the provider requiring non-standard Bind TON or NPI settings, which can also be specified on the "Advanced Settings" page. There is a bug in current versions of NowSMS where the "Address Range" parameter is not passed when a connection is tested (only when the service actually connects).
