Hello,

The uac_replace_from() function seems to be corrupting the To header in at
least some cases.

Here's an example.  A BYE comes in from a PSTN gateway with the following
headers:

To: "Anonymous" <sip:[email protected]>;tag=as12c6b8f1
Route: 
<sip:zz.xx.cc.yy;lr=on;ftag=as12c6b8f1;vsf=TXVycjImBhEvMDNhBxNPNhQ1MisgOhRHN
DAaTCEICg-->


After passing through Opensips, the To header reads (TN obfuscated for
privacy):

To:  "Anonymous" <sip:2160000000nwytww{e8b\valid>;tag=as12c6b8f1


Opensips then throws up some errors about this header:

 ERROR:core:parse_to: unexpected char [\] in status 6: <<"Anonymous"
<sip:2160000000nwytww{e8b>> .
 ERROR:core:get_hdr_field: bad to header
 INFO:core:parse_headers: bad header field
 ERROR:tm:t_check: reply cannot be parsed


The original invite's From header looked like this:

From: "Customer Name" <sip:[email protected]>;tag=as12c6b8f1


The config in use is as follows:

uac_replace_from("Anonymous","sip:[email protected]");

This gets run if certain flags are set that indicate the call is to be
anonymized.


Any thoughts?


Thanks,
Jeff
