FreePBX 18.104.22.168 + Asterisk 13.22.0
Registration of Telekom numbers: works OK, shows “Registered” (PJSIP)
Calling out always ends with 403-Forbidden - chan_sip AND pjsip.
There must be something wrong somewhere deep in the configuration.
all variations of username/password (there are several possibilities reported in various blogs…) do not work.
Asterisk is running behind a firerwall and NAT is needed. The external IP can be determined using the dyndns name of the external interface
I really don’t care whether I call out using chan_sip or pjsip - but corrently neither of them works.
Any ideas? There must be a solution, I’m sure …
