Re: [SR-Users] Kamalio call issue
Hello, Thanks for nice support. When kamalio is not working at some DNS with audio call then how we can know what is issue at client side? Can you give us any online communication like Skype or hangout ID? So we can check it is server or client side issue?

If the request gets to kamailio and cannot do dns requests or they don't resolve, you will see a sip reply from kamailio. There is not an issue that can be revealed by the config of kamailio. On the client side, try to use tools like host, dig and see what happens with dns requests. Also, use there ngrep to see if there are sip packets sent out of that box.

Re: [SR-Users] Kamalio call issue
Hello, look at the sip traffic on server to see if it is forwarded or not, and if yes, where. You can use ngrep, like: ngrep -d any -qt -W byline sip port 5060 Also, check your syslog file to see if any error message is printed there. It is not possible to guess what a fix would be if the real issue is not known.

If you don't see any INVITE on kamailo server via ngrep when you call, then the issue is on client side or there is a firewall dropping it.

Re: [SR-Users] Kamalio call issue
These are replies to INVITE requests, but if you see them, the INVITE passed through the server as well. If you are not aware of a firewall, then perhaps you don't have one unless is a default installation with it enabled or one on the network. I suggest you do sip tracing on the client machine to see if the invite requests leave to the proper IP. Ultimately can be also a problem caused by a NAT router with ALG, if the client is behind such device.
