Summary:                    [patch] Explicit context set in SIP peer overridden
by default domain context
Description: 
I'm running a couple of different internal domains in a multi-tenant
configuration.  SIP phones (SPA-942's and PAP2T's) register in their
respective domains, but have explicit contexts set per peer-definition (for
instance, the Fax hanging off the PAP2T can only 7 and 10-digit dial... it
has no international and no internal extensions).

In trying to support E.164 (ENUM) dialling, we tried to enable incoming
SIP calls to the domains by specifying a default context for each domain,
e.g.

domain=redfish-solutions.com,redfish-internet

in the configuration snippet below.  Unfortunately, doing this also puts
all of the internal SIP phones registering in that domain into the
redfish-internet context as well, which is neither desirable nor intuitive.

I posit that the proper behavior is to always use the "context=..."
specified in a [peer] SIP definition when present, and fallback on the
domain-associated context only when it isn't present.

Summary:

If "domain=redfish-solutions.com,redfish-internet" is commented out, then
calls made by "lab_1" use the [redfish-internal] context.  If it's
uncommented, then "lab_1" uses the [redfish-internet] context (making it
indistinguishable from an outside SIP caller [or hacker]).
