[SR-Users] Kamalio call issue

[Daniel-Constantin Mierla]

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.

Cheers,
Daniel
