Mersi mult Daniel! It worked but unfortunately it didn't fix the issue.
As I mentioned previously the original setup is like this:
Asterisk -> Kamailio gateway -> carrier. All calls go through just fine
The new setup we are trying is:
Asterisk -> Kamailio load balancer ( dispatch module ) -> Kamailio gateway -> carrier
With this setup the calls come back from the carrier with 500 - Internal error
I've looked at the SIP packets in both cases and they look similar. The only difference is that when going through the load balancer the To is different ( fixed now ) and it has 3 more VIA lines in the header. Where can I start looking at what's causing this ?
Thank you!

Changes are not immediately visible, this is the internal design from the time of SER back in 2001 -- I made a FAQ entry with more details:

In short, you have to use msg_apply_changes() function after changing headers.
Cheers, Daniel

Sorry if I repeat myself - I just subscribed properly to the list:
if you don't need to change it back for replies and next requests, try:
$td = "xyz.com";
IIRC, that is available on 3.2.x. If not, either you upgrade or use replace functions from textops.
Cheers, Daniel
Thank you for replying. We tried the direct assignment of $td="xyz.com" but the variable doesn't change. We are doing an xlog print right after and an ngrep and we confirmed that the domain part of the URI doesn't change. I also tried a subst() and it's the same problem. I read on the online documentation that the variable is read-only and I figured it can't be changed through these methods. That's why I tried uac_replace_to().
To sum it up, is that variable read-only or not ?
