Re: [EXT] Possible bug introduced in 5.8.5

Andreas,

This is the commit:
https://github.com/kamailio/kamailio/commit/6367a41f64ed165792ffe71ea310fd917947ccba

But are you sure you're not calling uac_replace_... twice per packet
processing? And for test - can you explicitly call msg_apply_changes()
after uac_replace_...() and check?
