I have been using the NMSS API for a few weeks now and I tried the samples with a real MMSC just to find out that the MMSC is an Ericsson and according to my knowledge there is no interoperability between NMSS and other vendors MMSC. This is quite disappointing as our solution is now near complete except for this problem. I am aware of a specification called mm7, will this allow interoperability, will it mean that I can use any vendor implementation and any vendor MMSC and be able to send MMS to a real mobile phone? If so, when will there be an mm7 implementation available? The documentation say that mm7 spec was due out summer of 2002. It is now April 2003, do we have an mm7 implementation just around the corner or will i have to wait much much longer. Any replies are much appreciated.
