Responding to myself: attached is an ngrep (made by homer/sipcature server). Some strange
things are happening. When I do a ngrep on the Kamailio, I see the ACK gets mangled:

restore_mode modparam is set to 'auto', and I checked that the vsf in
Route-headers are correct. Any clues?

Hi,
this last weekend we went live from the old 3.0 version to the latest stable release of
Kamailio (3,3,0). All went well, except for one issue. We make use of uac_replace_from in
our config, in case a client needs CLIR:
uac_replace_from("Anonymous","sip:anonymous@anonymous.invalid");
Since the upgrade we receive the following error:
uac [replace.c:521]: new URI shorter than old URI
Which causes the call to be disconnected after about 20/30 seconds. This, because the ACK
is received by Kamailio, but cannot be 'linked' to the transaction i guess.
What is exactly causing this issue and, more importantly, is there any way to resolve
this?
Thanks in advance,
Regards,
Ronald Voermans
