Hi, Attilas response is correct if a proxy receives an INVITE with out Max-Forwards header field. I think Navneet is saying "Endpoint"
Section 16.6 point 3 of RFC 3261 says "If the copy does not contain a Max-Forwards header field, the proxy MUST add one with a field value, which SHOULD be 70" In RFC 3261 I didn't find any description about what an endpoint should do if it receives with out Max-Forwards. I don't know which error code is correct but the proxies on the path are not behaving correctly.
