Hi!
I am in the progress of updating our asterisk 13.18.2 instance to 13.21-cert2.
This instance is inter-connecting several Mitel 400 PBXs.
Using Mitel 400 version 5.0 Hotfix 1 everything works well, with Hotfix 2 and 3 it always fails to authenticate when calling (register is fine). [EDIT: This is also a known-problem on 13.18.2 but I thought this might be a problem with PJSIP]
This asterisk instance is using PJSIP as channel driver. Is it possible to debug why the authentification failed?
Currently the error only shows “Failed to authenticate”. Wireshark/Tcpdump also only shows the 401 response.
Mitels support is incapable of processing bug reports to the devs. I would like to debug this error, as I am sure this is a problem on Mitels side, not asterisks or PJSIPs.
