[asterisk-users] Empty SIP Packet

Hello list,

                debugging SIP, I found many empty lines like:

<--- SIP read from UDP://XXX.XXX.XXX.XXX:5060 --->
<------------->

                The IP address above corresponds to one of my accounts, which is behind a firewall.

                Is that normal, maybe some firewall that tries to keep a port open, or is my firewall cleaning the SIP Packet?

Thanks in advance & best regards,

Alex
