Hi, I am trying to connect two Asterisk servers using IAX2. Everything works fine when I couple them within a LAN segment, but not when I connect them using WAN connections. I made sure that the routers' ports are mapped properly and checked this with additional ssh rules. ServerA is a Raspberry box with the vendor's Asterisk version 1.8.13.1 and ServerB is normal CentOS 7 box with Asterisk 13.1. Calling from ServerB to ServerA works, but not vice versa. The only odd thing that appears to me is the different perceived port on ServerA. ServerA*CLI> iax2 show registry Host dnsmgr Username Perceived Refresh State 80.152.xxx.xxx:4569 N ServerA 79.233.yyy.yyy:45697 60 Registered ServerB*CLI> iax2 show registry Host dnsmgr Username Perceived Refresh State 79.233.yyy.yyy:4569 N ServerB 79.233.yyy.yyy:4569 60 Request Sent Does someone have an idea at what to look in detail? jg

Currently, I am not sure whether it could be a NAT related or Asterisk configuration problem. jg
