As far as I know, there is no absolute limit on the value of Max- Forwards that a UA may use; except for processing efficiency, any finite number can be used. But if the request fails with Max-Forwards 70, it is unlikely to succeed with any larger value. For that to happen, the path from the sending UA to the target UA would have to have more than 70 SIP agents. So there is little value for the UA to re-attempt the request using a higher Max-Forwards. In practice, most UAs use Max-Forwards of 20 now rather than 70, and do not re-try the request if it fails with 483 Too Many Hops.
