All,

Can SER be used as a SIP A/S for example to write a carrier grade Ringback Tone application on top of SER.  

Does anybody know which media server (preferably OpenSource) to use?

Is SEMS the only way to write an application on top of SER or there are other ways?

Also, does anybody know how the applications in SEMS perform can they be deployed as a carrier grade solution?

Regards
