[SIPForum-discussion] Max forwards geting added by proxies

[Vijay Kumar]

Agreed as per RFC 3261 Sec 8.1.1.6   " Max forward is Mandatory header
feild in SIP Requests
UAC MUST insert it."

But as per 16.6

"If the copy does not contain a Max-Forwards header field, the proxy MUST
add
one with a field value, which SHOULD be 70."

My questions
1.If MAx forwards is a Mandatory parameter then why should proxy add it.(
If UAs are not able to add it).

2. As per 3261 if Max forward Is not added by UAC then SIP outbond proxy
Must add Maxforward header feild.
    Can Max-forwarded be added by intermediate proxies as wel l???

(If yes i feel the  purpouse of Max forwards header feild  does not serve
the purpose.)

Enlighten me please
Thanks in Advance
Vijay
