Deliver_SM not received on client
Posted: Thu Jan 23, 2014 9:46 pm
Hi,
We have the following problem
SMPP Perl client running on Linux doesn't receive all Deliver_SM, there are some lost packets
We think it is network problem at client but we are not sure
We captured 2 stream packets (posted bellow), first one received on client (trace1) and second lost (trace2)
Could someone give us help on this?
Thanks a lot!
