does the 503 reply include a retry-after header?
Does Kamailio behaviour depends on that header? If so IMHO it's not correct.
I've joined long discussions in sip-implementors about 503 with/without
Retry-After header. Some people think that a 503 without this header must be
considered as a 500. But after discussions this assumption is not correct and
a 503 must be considered similary even if it doesn't contain this header.
BTW RFC 3263 (Locating SIP Servers) says nothing about 500 error, neither
about Retry-After header in 503 replies. It considers a 503 with/without
Retry-After in same way.
IMHO Kamailio/SR should consider Retry-After just as informative but never
change the routing/failover behavior based on it.
Regards.
