When softphone register fs_cli fills up with Warning.

[Jean]

Hi,

This is a new install of Fusionpbx, never had this issue before. Every time a softphone or device register fs_cli fills up as bellow:

2019-02-01 06:07:19.419159 [WARNING] sofia_reg.c:1798 SIP auth challenge (REGISTER) on sofia profile 'internal' for [911@xx.xx.xx.xx] from ip xx.xx.xx.xx

Continuously then the softphone IP is rejected by fail2ban! Has anyone encountered this issue before?

Thank you

Sounds like client is behind a firewall with SIP ALG enabled. That's my gut reaction. Of course it could be something else...

Its almost certainly some sort of nat issue

 

[KonradSC]

See if the clients have a "rport" setting that you can enable.

Hi Guys, Sorry for my belated reply. Have checked my firewall, and yes the issue was there. As I was enabling NAT for external access it had some adverse effect, which I am not too sure why! But disabling it it stopped broadcasting that message in the console... Thank you @KonradSC @DigitalDaz much appreciated for your assistance.
