Hi
I have problem with some buggy hardware ATAs and routers, some of them mess
SIP requests by adding empty lines (\n or \r\n) between headers.
For example:
Via: SIP/2.0/UDP 80.1.1.1:5060;branch=z9hG4bKe89.28ac75a.0
To: sip:80.1.1.1
From: <sip:[email protected]
>;tag=13e3d64e25956fb4c1e2442af82fd0e3-c2c5
CSeq: 14 INVITE
Call-ID: [email protected]
Max-Forwards: 70
Content-Length: 0
Note empty line between CSeq and Call-Id. That's just example, empty lines
appear in random order.
I route calls to sippy B2BUA wich does not accept malformed requests and
throw exception in that condition.
Is it possible to detect such requests in OpenSIPS and remove unnecessary
empty lines from between headers?
Regards
