[OpenSIPS-Users] How to catch a "bad URI"?

[Bogdan-Andrei Iancu]

Hi Chris,

that is true - the problem is that along the RURI, the TO URI is also 
broken. And OpenSIPS is not able to construct the reply as it need the 
mirror the FROM, TO, CSEQ and CALLID headers.

As a generic way of catching parsing error , you can use the "error_route":

Bogdan
