This happened in part because I'm so far configure A-LAW on both sides so asterisk figures out it can do so. I still need to change IMS-core to EVS only. In any case, regardless of the codecs used, my understanding is that asterisk should never attempt remote bridging when using the "volte_ims" endpoint, since that network segment is separate from the local network where the local SIP UAs are located. The "direct_media=no" option just addresses the issue; Asterisk no longer tries to re-invite after the call is established Related: SYS#6782 Change-Id: I4edea96151b31f02bf292b43b757922389375429 --- M ttcn3-asterisk-ims-ue-test/asterisk/pjsip.conf 1 file changed, 28 insertions(+), 0 deletions(-) git pull ssh://gerrit.osmocom.org:29418/docker-playground refs/changes/51/36951/1 diff --git a/ttcn3-asterisk-ims-ue-test/asterisk/pjsip.conf b/ttcn3-asterisk-ims-ue-test/asterisk/pjsip.conf index 9400780..9ca85e5 100644 --- a/ttcn3-asterisk-ims-ue-test/asterisk/pjsip.conf +++ b/ttcn3-asterisk-ims-ue-test/asterisk/pjsip.conf @@ -106,6 +106,7 @@ rewrite_contact=yes from_user=238010000090828 from_domain=172.18.11.103 +direct_media=no [volte_ims] type=auth -- To view, visit https://gerrit.osmocom.org/c/docker-playground/+/36951?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: docker-playground Gerrit-Branch: master Gerrit-Change-Id: I4edea96151b31f02bf292b43b757922389375429 Gerrit-Change-Number: 36951 Gerrit-PatchSet: 1 Gerrit-Owner: pespin <pespin(a)sysmocom.de> Gerrit-MessageType: newchange
