[OpenSIPS-Users] Question about error 500 only via WIFI

Fri May 13 14:14:45 UTC 2022

Olá Rodrigo

The problem seems to be the IPV6 addresses. Did you look at the logs to
know exactly why opensips refused the call?

IPV4 is almost out in Brazil, mobile carriers are using ipv6 addresses on
mobile devices. This is the issue, but in theory opensips should handle
this seamlessly. Do you have IPV6 in your server or the message came on
ipv4 address but SIP has ipv6 addresses?

I recommend you check logs, the issue should be there. Also, if you plan to
allow mobile devices, you should be prepared to use ipv6 on your net.
