call drop because of no write codec, incompatible_destination

Hi,

I'm seeing multiple calls drop with incompatible_destination, i try to 
call again the same destination and it works fine. it gets me crazy...

In logs i see the error, "has no write codec",  in the capture i see the 
negotiation both sides have codecs, they are correctly configure in 
directory.

what could be causing this? i'm using version 1.8.6


Part of the LOG where the error happens:
