Hi Sir,
After having been able to setup playSMS on my local Ubuntu server as well as Kannel along with it, I was able to send sms but only through HTTP command, not playSMS. I went through all of the related topics in this forum, as well as in googleGroups for playSMS and other forums and still come out empty.
It’s driving me nuts. 
If you have any insights, please help… 
Tutorials I followed:
