Hi guys, I have a pre-sales question in regards to the NowSMS app. Once a bind is established (using SMPP over SSL) to the application, can the bind be kept up continuously?

Sorry ... we are not doing a good job of responding to questions here.

As long as the enquire_link timeout on the client is within the policy established by the SMPP server end of the connection.

If NowSMS is the client, then this timeout interval is the "Keep-alive interval" defined under "Advanced Settings" for the SMPP connection.

Basically, most SMPP servers will time out a connection if there is not some activity within a timeout interval configured at the server. The client is expected to send an enquire_link (keep-alive) packet at an interval less than this timeout if it wants to keep the connection open.

If NowSMS is the SMPP server, by default it will timeout a client connection if the client does not send a request (or enquire_link) every 120 seconds. This timeout is configurable under "SMPP Options" on the "Web" page of the NowSMS configuration dialog. If set to "0", it indicates that NowSMS will not timeout SMPP connections (this is not a good idea unless you've got an SMPP client application that just does not understand the concept).
