Hi,
I am using Kamailio 5.2.
Apparently the remapping of 503 to 500 codes in the tm module does also change the to-tag.
This behaviour breaks dialogs with yate and therefore calls hang and the 503 remains
unacknowledged. After disabling the 503 to 500 remapping with modparam("tm",
"remap_503_500", 0) all works fine again.
Changing the to-tag in a dialog seems to contradict RFC3261, or do I see this wrongly?
12 <https://tools.ietf.org/html/rfc3261#section-12> Dialogs
A dialog is identified at each UA with a dialog ID, which consists of a Call-ID value, a
local tag and a remote tag…"
Thanks for looking into this.
Gerry
