This depends on the SMSC, one of my SMPP connections is set to 30, others are set to 5, while another connection is balanced to 3 connections each one has a max-pensing-submits=25 (75 in total)
Try to increase it and monitor the delivery of the messages, make sure there is no drops and define your real limits. By the way, the default max-pending-submits is 10 Best Regards, Mohammed M I Sleem http://www.abusleem.net - Personal blog http://www.freakle.com - The Search Freak <http://www.colorle.com> On Thu, Dec 16, 2010 at 3:56 PM, Rapture <supp...@ims.co.ke> wrote: > Thanks Saleem, > > > > I have set the max-pending-submits to 10 per SMSC connection and my limit on > the SMSC side is 100MTs per second.
