</div><pre style="font-family: monospace,monospace; white-space: pre-wrap;">chan_pjsip: Fix ability to send UPDATE on COLP<br><br>When connected_line_method is "invite", we're supposed to determine<br>if the client can support UPDATE and if it can, send UPDATE instead<br>of INVITE to avoid the SDP renegotiation. Not only was pjproject<br>not setting the PJSIP_INV_SUPPORT_UPDATE flag, we were testing<br>that invite_tsx wasn't NULL which isn't always the case.<br><br>* Updated chan_pjsip/update_connected_line_information to drop the<br> requirement that invite_tsx isn't NULL.<br>* Submitted patch to pjproject sip_inv.c that sets the<br> PJSIP_INV_SUPPORT_UPDATE flag correctly.<br>* Updated pjsip.conf.sample to clarify what happens when "invite"<br> is specified.<br><br>ASTERISK-27095<br><br>Change-Id: Ic2381b3567b8052c616d96fbe79564c530e81560<br>---<br>M channels/chan_pjsip.c<br>M configs/samples/pjsip.conf.sample<br>M res/res_pjsip.c<br>A third-party/pjproject/patches/0070-Set-PJSIP_INV_SUPPORT_UPDATE-correctly-in-pjsip_inv_.patch<br>4 files changed, 48 insertions(+), 6 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;">diff --git a/channels/chan_pjsip.c b/channels/chan_pjsip.c<br>index d1691b8..e2fd13c 100644<br>--- a/channels/chan_pjsip.c<br>+++ b/channels/chan_pjsip.c<br>@@ -1272,8 +1272,7 @@<br> int generate_new_sdp;<br> <br> method = session->endpoint->id.refresh_method;<br>- if (session->inv_session->invite_tsx<br>- && (session->inv_session->options & PJSIP_INV_SUPPORT_UPDATE)) {<br>+ if (session->inv_session->options & PJSIP_INV_SUPPORT_UPDATE) {<br> method = AST_SIP_SESSION_REFRESH_METHOD_UPDATE;<br> }<br> <br>diff --git a/configs/samples/pjsip.conf.sample b/configs/samples/pjsip.conf.sample<br>index d908119..f983a87 100644<br>--- a/configs/samples/pjsip.conf.sample<br>+++ b/configs/samples/pjsip.conf.sample<br>@@ -608,8 +608,15 @@<br> ;direct_media_glare_mitigation=none ; Mitigation of direct media re INVITE<br> ; glare (default: "none")<br> ;direct_media_method=invite ; Direct Media method type (default: "invite")<br>-;connected_line_method=invite ; Connected line method type (default:<br>- ; "invite")<br>+;connected_line_method=invite ; Connected line method type.<br>+ ; When set to "invite", check the remote's<br>+ ; Allow header and if UPDATE is allowed, send<br>+ ; UPDATE instead of INVITE to avoid SDP<br>+ ; renegotiation.
