in the smsc group validityperiod in minutes in general the smsc use its default validity period except in the cases you explicitly have set a value per SMS : http://kannel.org/download/kannel-userguide-snapshot/userguide.html#AEN4295 validity=1440 i.e. 24 hours deferred parameter is hated by the smsc in 99% of the cases so in 99.99% of the cases the smsc returns error in case the parameter is not NULL simple reason: you may use that feature to crash it down in short, check first with your telco before to use deferred parameter. -----Original Message----- From: [email protected] [EMAIL PROTECTED] Sent: 24 Януари 2008 г.
