Description:When I use SRVlookup, every register the Asterisk send REGISTER to other IP.
It should send the REGISTER message to the server it send register last time.

sorry it's not every time it's quite random

If I understand you right, this is by design. A domain can have multiple SRV records with different server names, the DNS server authoritative for that domain can respond arbitrarily with any server it likes. Asterisk will cache the response for the amount of time configured in the DNSMGR config file, after that it will issue a new query and use whatever is returned in the response to that query.

yes, this is a bug. Asterisk should stay with the srv record choosen until it fails, not pick a new one each time.

ok it works, thanks. However i think it should stay with the last register server till it fails

Ebroad: Why assign it to me?

This may still be an issue, but I'd be interested if this can be reproduced on Asterisk 1.8?

I'm running Asterisk 1.8.4-rc3 and I see this:

I don't know if Asterisk is actually re-registering to the different Callcentric servers or not, so this may be irrelevant.

Issue still exists in 1.8.4.2
By: Luke H (luckman212) 2011-09-25 23:53:39.829-0500

This is still the same behavior in 1.8.7.0 (rel).  Seems to me this is related to ASTERISK-17722

Im having this same issue on asterisk 10.6.1 that is running on ubuntu 11.10
