Hello, there was an old thread bout this topic:
Now I need to pull this up again, as Telekom now has deleted its A-Record for tel.t-online.de so that the SRV frecords must be used. As I understand this old thread, I need to use one of the three names returned in the SRV lookup as the “SIP server” in the pjsip dialog and leave the port part empty? However, I always get
res_pjsip_outbound_registration.c: tk-XYXZ-0123456789: 403 Forbidden fatal response received from ‘sip:h2-epp-110.edns.t-ipnet.de’ on registration attempt to ‘sip:firstname.lastname@example.org’
Maybe I have not understood correctly why I need to setup an own zone for this. We are not using BIND, so I cannot apply this recipe directly. Am I righth that we need to tell the DNS server to always return the same SRV answer if a requst goes to " _sip._udp.tel.t-online.de" and that I need to enter " _sip._udp.tel.t-online.de" into the PJSIP dialog??
