This is why the rfc recommends 70 as the default value.<div><br></div><div><pre style="word-wrap: break-word; white-space: pre-wrap;">8.1.1.6 Max-Forwards
The Max-Forwards header field serves to limit the number of hops a
request can transit on the way to its destination. It consists of an
integer that is decremented by one at each hop. If the Max-Forwards
value reaches 0 before the request reaches its destination, it will
be rejected with a 483(Too Many Hops) error response.
<b>A UAC MUST insert a Max-Forwards header field into each request it
originates with a value that SHOULD be 70.</b> This number was chosen to
be sufficiently large to guarantee that a request would not be
dropped in any SIP network when there were no loops, but not so large
as to consume proxy resources when a loop does occur. <b>Lower values
should be used with caution and only in networks where topologies are
known by the UA.</b></pre><div><br></div></div><div><br><div><div>On Apr 28, 2014, at 5:13 PM, Rafael Kaihatu <<a href="mailto:rafael.kaihatu@8x8.com">rafael.kaihatu@8x8.com</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div dir="ltr"><div class="gmail_quote"><div dir="ltr"><div><div><div>Hi,<br><br>issue description:<br>inbound call arrives with Max-Forwards set to 9 (or some low value), after the 9th internal transfer (it executes the transfer command, but the call doesnt leave the freeswitch instance), the call is dropped.<br>
