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 ?
