generic front end for Kannel

Hello all,

I know it is not directly related to kannel, but I'm looking for a
entreprise grade frontend (opensource or licence paid) to use with kannel.
Do someone has some experience with existing system ?

Here are the existing system I know :
	- playsms,
	- smppcube
	- joomla + jeema

Any others ?
Any feedback on them ?

Thanks in advance
