So I don't use pjsip... :(
Maybe could you send me an abstract of your configuration?

So if I undestand what you mean, you check the NAPTR and SRV für
_sips._tcp.tel.t-online.de and save the record in a "virtual domain"
rpz-tonline, is it correct?
Then I suppose you use this domain instead of tel.t-online.de in the SIP
configuratione as "host", "outboundproxy" and "fromdomain", is it correct?

OK, I'll check it...

Could you explain me that? I'm not an expert of Asterisk... :(

Thanks a lot!
