<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I think this is a good case for using "is" instead of equality. I imagine that callers of this function are going to be passing a reference to the same account object that is stored on the phone_obj rather than a separate object with equivalent properties.
Also, to avoid the continue statement, you can just use a positive comparison instead of a negative one:
if account is phone_obj.account:
return phone_obj</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">A couple of PEP 8 points:
1) When catching exceptions, use the syntax "except ErrorType as ErrorInstance" instead of "except ErrorType, ErrorInstance". So here, it would be "except pj.Error as err"
2) A PEP 8 checker will complain about the indentation of str(err)) on the final line I've highlighted. It will claim it should be lined up like this:
raise Exception("Exception occurred while making call: '%s'" %
str(err))
See how "str" is lined up to show how it belongs to the parentheses?</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This seems overly complicated for what you are trying to do here. Why not just
try:
self.phone.calls.remove(self.call)
except ValueError:
# Log an error or something
If that doesn't work because equality of calls doesn't evaluate as you'd expect, then this is a situation where I expect that a single object reference is being passed around everywhere rather than separate call objects. You could take the approach of reconstructing the self.phone.calls list like this:
self.phone.calls = [call for call in self.phone.calls if call is not self.call]</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">The first suggestion is actually what I initially was using. However I found that the call object wasn't always being removed from the list. Debugging showed the id() of self.call not matching any in the list which I believe is because self.call is set to weakref.proxy(call) in pjsua.CallCallback(). Comparing the SIP Call-ID of the call objects should be unique enough to find the one to remove from the list.</pre>

1) Be renamed to something indicating that it is just gathering call information into a string
or
2) Be altered to actually log the call info using LOGGER.debug()</pre>

Apparently a lock isn't needed when making call. Unless perhaps a callback isn't passed and then set later using call.set_callback() but that's not the case here.</pre>

If it remains with the same scenario then things won't blow up and no user code is called into(maybe there's a need for that?). Suggestions?</pre>

Calls are placed and/or transferred using the new pluggable action module. This should allow many currrent and future tests to easily send/receive calls to/from Asterisk along with transferring calls within YAML configuration.
The pluggable test module (phones.PjsuaPhoneController) initializes the PJSUA accounts and once all have registered, the account callbacks are setup and are ready to receive calls. The pluggable action module (pluggable_modules.PjsuaPhoneActionModule) provides the ability to place calls and transfer calls using the accounts from YAML and the action is referenced with 'pjsua_phone'. The only time a call is hung up by this is when a transfer is performed and a 200 OK sipfrag NOTIFY is received. None of the modules set a pass/fail result and are only for driving and manipulating calls.
