Hello everybody, I am configuring a gateway after a forced migration to new voip service provider, and I got the registration working and I can make incoming and outgoing calls, but the gateway always stops working after a while. I do not see any incoming invites any more when trying to reach the number. Does someone know how to debug or solve this? The only hint I can find in the logs is this: 2022-05-06 16:13:29.518588 91.40% [DEBUG] sofia_reg.c:2745 Missing Authenticate Header! emily:~# cat /etc/freeswitch/sip_profiles/external/provider.xml <include> <gateway name="provider"> <param name="auth-username" value="aaba37818192@ims.imscore.net" /> <param name="username" value="+31105221234" /> <param name="extension" value="0105221234" /> <param name="password" value="secret" /> <param name="realm" value="ims.imscore.net" /> <param name="register-proxy" value="voip1-ext.kpn.net" /> <!-- <param name="realm" value="ims.imscore.net" /> <param name="proxy" value="ims.imscore.net" /> <param name="outgoing-proxy" value="voip1-ext.kpn.net" /> <param name="register-proxy" value="voip1-ext.kpn.net" /> <param name="expire-seconds" value="1800"/> <param name="retry-seconds" value="30"/> <param name="ping" value="20"/> --> <param name="expire-seconds" value="1800"/> <param name="register-transport" value="udp" /> <param name="register" value="true" /> <param name="context" value="public"/> <param name="log-auth-failures" value="true"/> <param name="debug" value="1"/> </gateway> </include> emily:~# fs_cli -x "sofia status gateway provider" ================================================================================================= Name provider Profile external Scheme Digest Realm ims.imscore.net Username +31105221234 Password yes From <sip:+31105221234@ims.imscore.net> Contact <sip:gw+provider@77.169.195.30:5080;transport=udp;gw=provider> Exten 0105221234 To sip:+31105221234@ims.imscore.net Proxy sip:ims.imscore.net Context public Expires 1800 Freq 1800 Ping 0 PingFreq 0 PingTime 0.00 PingState 0/0/0 State REGED Status UP Uptime 189s CallsIN 1 CallsOUT 0 FailedCallsIN 0 FailedCallsOUT 0 =================================================================================================
