<p class="MsoNormal"><span lang="EN-US" style="color:#1f497d">Finally we discover the problem why the calls were stalled in state::1, we do several checks before an INVITE is t_relayed(), this seems to be too much for certain clients and then they send a INVITE with the same call-id, this was generating “state::1” dialogs. We solve this issue by sending a “100 – Trying” right after the INVITE arrives to the proxy, in this way the caller don’t send a new INVITE… it worked like a charm.</span></p>
<p class="MsoNormal"><span lang="EN-US" style="color:#1f497d">Now we’re trying to see how we can handle certain situations where “state::3” dialogs are kept in memory. This happened with this type of calls :</span></p><p class="MsoNormal">
