First I would like to thank for the cool application I use within VB6 it work perfect 

My question?
Is it possible or how to sendwave file with best quality I notify that if I set CAPI block size of 480 (default) the quality is OK but I don't know what is the best ? or is it possible to be mp3 format in the future.
 
Thanks.

(PS:because of it too many unknow parameter to set with Phoner I think if PhonerLite can sendwave it may benefit to use)

Stranger for me if I set block size to 2040 (max) the play sound on other side when receive are uncontinuous sound (I play ansage.wav) and if set to minimum 240 if has noise intefere and with the perfect sound at 480 or 960. So it may be with my sound card ??? no problem I decide to use 960 and hope it not disturb any function of Phoner.

I found 3cx free edition it look the same as Phonerlite (may be twin ).

I make the pilot program with use Phoner my program will make a call to doctor when the patient has some critical data whice the VB6 will automatic read from database and make a call direct to each doctor mobile phone and play the pre record wave file which coresponsetence the suitiation thank for the help of Phoner free programe it make my project perfect with payless.

Hi. The new beta work perfect sound quality is better than ever thanks.

And can you add sound background sound may be play from mediaplayer I think it look sweet if we make a call and play some light music for backgound (optional) it make the conversation good.
