After some more careful testing i found that sipnet does not support "reinvite without sdp". In reply to such "reinvite without sdp" they send ack and then after a while 408. I'll ask them if they are going to fix it, but right now there is no sence in spending efforts for the sake of compatibility with them. Rgds, Nikolay.

But they always send dtmf via Info. That is the only problem is to receive dtmf via Info.

It is not possible to make them change their mind and use 2833.... There are about 15 ip pbx vendors listed in sipnet compatibility list. I believe sipx should (even must) be there.... Except dtmf, sipx looks to work ok with sipnet. Now when sipx AA is actually FS, it should be quite easy to enable sipx to receive dtmf digits via sipinfo. I know that sipxbridge does not allow method Info. Is there a simple way to make sipxbridge to pass Info messages? What could be done to current AA / VM to make it understand dtmf via Info? Should i raise an improvemnet issue? Thanks and regards, Nikolay.
