Summary:                    chan_sip loses registration and peer information
after dnsmgr refresh
Description: 
It seems to be related to the DNS refreshing on the system, but when that
happens, my peers will often become unreachable for outbound calling while
inbound calling seems to be fine.

The main indication of this is when you run 'sip show peers' you'll see
the port has been set to 0 (zero) even though the port=5060 setting is part
of the peer definition in sip.conf.

I've seen other reports of this on #asterisk today as well. May be related
to the other dnsmgr issues in chan_iax2 etc..?

More information after testing and data requested by russell:

To reproduce this, I did the following:


sip.conf:

<ul>
<li>started with udpbindaddr=216.x.x.x:5060
<li>sip show peers
<ul>
<li>all peers show port set to 5060
</ul>
<li>changed sip.conf to have bindaddr=:: and commented out udpbindaddr
<li>sip reload
<li>at this point the ports are all changed to 0
<li>even after a dnsmgr refresh I still have ports set to 0
</ul>
