Function Documentation

static int mod_init

(

void

)

[static]

The initialization function, called when the module is loaded by the script. This function is called only once.

Bind to the dialog module and setup the callbacks. Also initialize the shared memory to store our interninal information in.

Returns:

0 to continue to load the Kamailio, -1 to stop the loading and abort Kamailio.

   {0,0,0,0,0,0}
}

int sst_flag = -1 [static]

The sst message flag value

unsigned int sst_minSE = 90

The default or script parameter for the requested MIN-SE: value for this proxy. (in seconds) If the passed in value is 0, then this proxy will except any value from the UAC as its min-SE value. If the value is NOT set then the default will be asserted.

unsigned int sst_reject = 1

Should the PROXY (us) reject (with a 422 reply) and SE < sst_minSE requests is it can. Default is YES.

pv_spec_t timeout_avp

The name of the AVP the dialog module will use to hold the timeout value so we can set the AVP in the dialog callbacks so the dialog code will set the dialog lifetime when it returns from the INVITE and IN_ROUTE callbacks.

char* timeout_spec = 0 [static]

Place holder for the passed in name
