[asterisk-users] Improving Asterisk's DNS support

[Kristian Kielhofner]

Hello everyone,

  After several years of using Asterisk I have always been frustrated
by the support for DNS.  I have seen all kinds of strange behavior
when Asterisk is used on a system with "iffy" DNS servers:

- no failover to other DNS servers in /etc/resolv.conf (might be a C
library thing)
- chan_sip will sometimes mark even local SIP peers as unreachable
during/after any DNS problems - why?
- dnsmgr doesn't support SIP (yikes!): http://bugs.digium.com/view.php?id=9153
- other randomness (please contribute your own experiences)

  What can we do about improving this situation?  At the very least we
need to extend DNS manager support to SIP.  I'm willing to pay for
this and any other Asterisk DNS improvements.  Any other ideas?
