[Kamailio-Devel] Nathelper SDP message parsing from the Nortel softswitch

[Andrew O. Zhukov]

I have 2 questions:

1. Can someone try to parse invite message with multipart content in 
Mediaproxy?
2. Is it possible to fix a parsing of this kind of message in the 
nathelper module?

I got the followed error set:
ERROR:nathelper:check_content_type: invalid type for a message
ERROR:nathelper:extract_body: content type mismatching
ERROR:nathelper:force_rtp_proxy2_f: can't extract body from the message
.....
ERROR:nathelper:force_rtp_proxy2_f: incorrect port 0 in reply from rtp 
proxy
