Hi, Does any body know or has test the "a1-hash" parameter with gateway setting? I am not sure if it is even allowed. I have the following gateway setting but when the freeswitch starts up it simply ignores this provider without any error message or attempt to register in the log file. Thank you for your help in advance. <include> <gateway name="iptel"> <param name="username" value="MY-USERNAME"/> <param name="realm" value="iptel.org"/> <!-- <param name="password" value="MY_PASSWORD"/> --> <!-- replaced the password with MD5 encrypted --> <!-- openssl dgst -md5 < filename, or echo "username:domain:password" | openssldgst -md5 --> <param name="a1-hash" value="30f610a85e973f2b29b75ddc1ec3450e"/> <param name="proxy" value="sip.iptel.org"/> </gateway> </include>
