Dear all, This is the SDP from my GW, Content-Length: 209 v=0 o=CiscoSystemsSIP-GW-UserAgent 8228 4523 IN IP4 9.13.38.50 s=SIP Call c=IN IP4 9.13.38.50 t=0 0 m=audio 18368 RTP/AVP 0 19 c=IN IP4 9.13.38.50 a=rtpmap:0 PCMU/8000 a=rtpmap:19 CN/8000 a=ptime:20 I need to caculate MD5 hash of Entity body thro TCL/Unix API and compare it with what my GW generates.The GW generates it as, H(entity-msg)= 7e926cfa696deb5a1e40ee4ed8ad81d1 The following online tool(http://md5-hash-online.waraxe.us/) also generates it as 7e926cfa696deb5a1e40ee4ed8ad81d1. I am using a windows based MD5 commandline tool used like this md5 filename = 7e926cfa696deb5a1e40ee4ed8ad81d1. So my GW and two of the tools are generating the same value.The issue here is, I need to do this in UNIX commandline or using TCL Lib so when i use same SDP in unix Environment using MD5sum or TCL lib md5::md5 -hex -file filename or md5::md5 -hex "string".The Hash i get is always different from that of ONLINE TOOL and windows based TOOL.The o/p of Unix MD5sum and TCLLib MD5 api are always same. Pls advice what am I missing UNIX why its not matchig with windows based on Online TOOL.
