I am using SMPP with PHP for sending and receiving messages. I got this error when i am trying to send a message. what is the cause of this and how can i send a message ? thanks.
pfsockopen() [function.pfsockopen]: unable to connect to sms.korewireless.com:2777 (A
connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. )
Your program tries to connect to remote server, but fails to do it before timeout elapsed.
There could be plenty of reasons for this: server may be not listening this port, your firewall forbids access to it and so on.
Try to connect to that server using telnet to find where problem is.
SMPP usually needs a bind into their server from yours. This could include whitelisting IP's, User/Pass, etc... I would contact their help desk as it sounds to be a configuration error either on your side or theirs.
