[OpenSIPS-Users] B2B module and CANCEL

[Anca Vamanu]

Hi Denis,

We hit this problem also some time ago, it was indeed a bug when 
applying lumps in local_route. We were just waiting for the fix to get 
enough testing. It is stable now. I have just committed the fix in tm 
module in both trunk and 1.6. Please upgrade and check.

Regards,
Anca
