Is there any way to implement http connector for sending messages(MT) in Jasmin? According to documentation jasmin HTTP API supports smpp connector only.  
Update 1:
More information of scenario:
I have 4 sms providers that I need to implement using Jasmin.
one of them is using SMPP protocol and is working fine with jasmin using smpp connector.
Other 3 have http protocol (call url with params to send SMS).
I want to use http protocol with jasmin to use its routing and other stuff.
Jasmin only supports HTTP client connectors for MO (mobile originated) messages. 
Having found myself with the same scenario as yourself, I found the simplest solution was to write an SMPP-to-HTTP service which allows Jasmin to connect to it and relay MT messages via HTTP. Hope that helps
