Hi All, I have a 7270 (firmware 54.04.70 with SIP registrar) and Siemens Gigaset A580 IP. I tried to register A580 on 7270 (extension 620) but I received always "registration failed". I tried registration on 7270 (extension 620) with GS HT 503 and it was successfully. I cannot debug voipd "voipd -v -o 10" does not work anymore. Any idea?
