Okay, I'm trying to use uac_replace_from to anonymize the From: in order to
suppress ANI. I think I've got it, but it seems like the behavior isn't what
I expect. First, the relevent config file section:
if (search("Anonymous")) {
uac_replace_from("","sip:anonymous@xxxxxxx.com");
append_rpid_hf("",";party=calling;id-type=subscriber;screen=yes;privacy=full");
log(1,"Made a call anon");
};
Now, the headers as they go in and come out:
SIP MESSAGE 4 xx.7.96.185:5061() -> xx.7.96.82:5060()

And finally what I'm seeing in the log:
Jun 30 08:18:33 voip02 /usr/sbin/ser[4684]: DEBUG:uac:replace_from:
removing display [Anonymous]
Jun 30 08:18:33 voip02 /usr/sbin/ser[4684]: DEBUG:uac:replace_from: uri
to replace [sip:+136091xxxxx@voip02.xxxxxxxx.com]
Jun 30 08:18:33 voip02 /usr/sbin/ser[4684]: DEBUG:uac:replace_from:
replacement uri is [sip:anonymous@xxxxxxxx.com]
So what am I missing here? It looks like uac_replace_from is finding the
right URI and replacing it, just not properly. I've already gone into CVS
and I don't see any relevent changes.
Any help? Please?
