[OpenSIPS-Users] reason headers

[Vlad Paiu]

Hello,

What you are doing is pretty unsafe.
Search and Replace do not work at header level, but will match any 
string within the SIP msg, such as a 'reason' URI parameter, or whatever 
else, so you might end up in overwriting something else.
The textops module has functions that operate at SIP header level.

Check is_present_hf [1], remove_hf [2] and append_hf [3]. So basically 
what you want to do is, if the header is present, get it's body, remove 
it, and add a new header, called differently, but with the same body as 
the previous one.
