<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Currently, the udptl object is allocated in one of three places:
1) create_addr_from_peer
2) sip_alloc
3) handle_request_invite
This typically results in any dialog associated with a peer that supports T.38 having a udptl object (and its associated UDP ports, system resources, etc.) assigned to it. This includes non-INVITE requests.
This patch moves the initialization of a dialog's udptl object to either (a) when the media is negotiated for that dialog, or (b) if a control frame is received in chan_sip indicating that the dialog needs to support T.38. This should result in only those dialogs that are explicitly involved with sending / receiving image media having a udptl object assigned to them.</pre>

[update] - ported the patch to Asterisk 10 and tested with the Test Suite's gateway tests. All tests passed.
However, given the complexity and number of ways in which media can be negotiated, additional testing would be appreciated from the open source community.</pre>
