I’m having problems with sip. I cannot register with the provider’s server, either with softphones or ata device.
The credentials are correct, since I can connect with a celular phone running a softphone installed.
I have port forwarding in the firewall with a rage of udp ports for rtp and port 5060 udp, although I don’t know if this is necesary as a client.
I read since core 155, alg has been eliminated for security reasons. Can be this part of the problem? How can I fix this?
