When you start Kannel, it attempts to start all the configured SMSC binds. While this is usually what most people needs, there might be some cases when you don’t want all your binds to come up at once:

• Failover routes that you manually enable when needed.
• New binds being worked out, not ready for production.
• Test binds you use only from time to time.
• Etc.

This patch allows you to configure in which state a bind will start when booting (or when adding it with the add-smsc command). This is done by a new parameter on the smsc group called start-at-boot, which defaults to true if not present.

In short: just add the following line to an smsc group:

start-at-boot = false

and that smsc will start as “dead” and will require a start-smsc command to activate it.

As usual, this is fairly untested code and should be used with caution.

Please try it and let me know if you encounter any issues.

This patch allows you to change the parameter names used when receiving incoming messages (MO’s) using the generic http-smsc.

To use it, you need to add a few extra entries for the parameters you want to be redefined. The format is: generic-param-<original-name> = <new-name>

For example, to redefine from, to, smsc and text:

generic-param-from = “phoneNumber”
generic-param-to = “shortCode”
generic-param-text = “message”
generic-param-smsc = “carrier”

That’s it, you’ll be able to use an url like this then:

http://myhost:myport/sms?phoneNumber=234567890&shortCode=1234&message=Hello+World&carrier=mycarrier

NOTE: This patch was superseded by another one I’ve wrote that adds smsc-admin-id instead. The smsc-admin-id patch was already commited to CVS so the use of the smsc-dlr-alias is now officially deprecated.

A problem you may have faced with dlrs on Kannel: If you’re using dlrs and have more than one bind to a given carrier, you need to name them all the same. Otherwise, if the dlr come back over a different bind than the one you’ve used to send the MT message in the first place, Kannel won’t be able to match them, since they won’t share the same “smsc” field.

This is usually OK. However, you lose the ability to control the binds independently: you cannot shutdown a single bind, for example. The problem worsens yet more if your binds are to different data centers (some carriers have redundant SMSC’s on geographycally distant places).

That’s why I’ve created this patch that adds a new configuration option to SMSC groups:

smsc-dlr-alias

Using this parameter, you can define an alias to use when storing dlrs, so they will match despite being sent/received over different binds.

For example:

…

#carrier link 1

group                      = smsc

smsc                       = smpp

smsc-id                  = “link1″

smsc-dlr-alias     = “myalias”

allowed-smsc-id = “link1;mylink”

host                        = “1.1.1.1″

…

#carrier link 2

group                      = smsc

smsc                       = smpp

smsc-id                  = “link2″

smsc-dlr-alias     = “myalias”

allowed-smsc-id = “link2;mylink”

host                        = “1.1.1.1″

…

Using this configuration, you just have to use the “&smsc=mylink” parameter on your send-sms url. The dlr will be stored using the alias “myalias” no matter which of these 2 routes the message takes. When getting the response back, again, it will be matched against “myalias”.
