Hello,

the problem here seems to be the update of To header. Are you changing the To URI as well? I don't see the parameter for it in the Route header.

From URI handling seems to be ok.

Cheers, Daniel

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

Hello,

can you look at execution traces printed by debugger module just ot be sure no subst/replcae function is executed there?

I will have to look at sources to see if there is a side effect in uac replace from that affect the two header. Also, can you use the latest 3.3.x (3.3.4 or git branch 3.3) just to be sure it is not the effect of an fixed issue (you mentioned 3.3.0 as your used version).

Cheers, Daniel

Hi Daniel,

Thanks for your update. No, I'm only changing the from header. The to-header URI is not touched. The R-URI is however (there's a prefix added). When the ACK is being sent, syslog adds a message 'New URI shorter then old URI'.

Regards,

Ronald
