[asterisk-users] asterisk 1.6 - doing dnsmgr lookup for... / call fails

[Joseph]

I just jumped to asterisk-1.6.1.8 and I calls will not go through to my asterisk.
Same setup with asterisk-1.4 and calls get accepted.

sip show registry (asterisk-1.6):
Host                  dnsmgr  Username   Refresh  State
sip.actio.pl:5060     N       4589835        105  Registered

sip show registry (asterisk-1.4):
Host                  Username   Refresh  State
sip.actio.pl:5060     4589835        105  Registered


The only difference I see is that asterisk-1.6 has dnsmgr ? and I get a lot of lines showing:
"doing dnsmgr_lookup for 'sip.actio.pl'

What is this "dnsmgr"; is it a reason for failed calls?
