[Freeswitch-users] Reinvite Issue / no SDP

[Stefan Kainz 1012]

Thank you for your answer!

after investigating a few different cases, i came to the following 
conclusion:
Some PBX's seem to not to accept the SDP Offer in the OK Message when 
the Session Version ID is not increased from the SDP Version ID in the 
initial Call Setup.

Ever heard of such a behavior?
What would you suggest to get by this issue?

I also testet it on Version 1.6 and 1.6.17. Same issue here.

Thank you in advance!

regards,
