Version: 2.5.5~dfsg-6
Severity: important
Tags: patch upstream
While trying to use Asterisk with its newer PJSIP-based SIP channel
support, it turned out that registering to a SIP server fails if the SRV
targets do not have an record, but only an A record.
The effect, which can be seen via Wireshark, is that essentially no SIP
registration is taking place at all, after all necessary DNS requests
have been sent out. Asterisk then just says:
No response received from 'sip:xxx' on registration attempt to
'sip:xxx@xxx', retrying in '30'
After some debugging it became clear, that the DNS resolution is
successful as far as resolving the A records of the SRV targets. However
in case a SIP server does not have an record, libpjlib-util2
skips/aborts the whole resolution and treats it as failed, no matter if
an A record has been found or not.
Applying upstream's GitHub commit 4ab1838 (part of pjproject 2.6) onto
Debian stable's version 2.5.5 solves the problem.

Conclusion: Please apply the mentioned patch and release a new stable
version.
