I am facing the problem where one of source is sending bunch of RTP payload in 
"mline", and because of that my MSX is stripping 2 codec from that line, when 
its forwarding that OFFER to termination end.

This is the "mline" which i am getting from source:

m=audio 6300 RTP/AVP 18 0 8 35 36 2 38 39 40 41 42 43 44 45 46 47 4 80 3 56 118 
101 13 120

This is what my MSX is sending to termination after stripping the payload from 
"mline"

m=audio 6300 RTP/AVP 18 0 8 35 36 2 38 39 40 41 42 43 44 45 46 47 4 80 3 56 118 
101

Now i checked some documents but unable to find anything which says its correct 
or not.

The input SDP is correct, of course.  If the MSX's purpose is to limit the 
number of codecs that the session may use, or to eliminate the use of the 
codecs identified by 13 and 120, then it has succeeded.  If its purpose is to 
be transparent for SIP usage, its behavior is erroneous.
