[asterisk-bugs] [JIRA] (ASTERISK-25528) DNS TTL parse error

[Rusty Newton (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-25528?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Rusty Newton updated ASTERISK-25528:
------------------------------------

    Description: 
Trying to register to a SIP cluster using NAPTR/SRV records fails due to DNS lookup failures. The failures are due to incorrect parsing the TTL for the records.

sip.itco.nl has both NAPT and SRV records (with short ttls (300)), The real edge proxies (sip[01].itco.nl)) have a longer ttl (86400). Responses aren't added to the result set with debug responses:
{noformat}
dns_core.c: Query '0x7f66cc00a3c8': Could not add record, invalid TTL '-822083584'
{noformat}
