BYEs, 200s and Terminated Dialog.

[Hojo]

Hi,

I am currently testing a B2B SIP servlet and having some issue with SipUnit closing down the dialog. Following an example in another post I created a BYE by hand and waited for the response:

...
LOGGER.info("TEST: {}", sipCallB.getDialog().getState());

final Request bye = sipCallB.getDialog().createRequest(Request.BYE);

final SipTransaction trans = sipPhoneB.sendRequestWithTransaction(bye, false, sipCallB.getDialog());
assertNotNull(trans);

LOGGER.info("TEST: {}", sipPhoneB.format());

assertNotNull(sipPhoneB.format(), trans); // request sending was ok
final EventObject respEvent = sipPhoneB.waitResponse(trans, TIMEOUT);
LOGGER.info("TEST: {}", sipCallB.getDialog().getState());

LOGGER.info("TEST: {}", sipPhoneB.format());

assertNotNull(sipPhoneB.format(), respEvent);

assertTrue(respEvent instanceof ResponseEvent);
final Response resp = ((ResponseEvent) respEvent).getResponse();
assertEquals(Response.OK, resp.getStatusCode());

...

Which works and my application gets the BYE request. The problem is when the servlet responds with a 200 OK it complains because the dialog is terminated, which I can see from the output:

INFO - SipB2BCallSteps - SipB2BCallSteps.java 168 TEST: Confirmed Dialog
INFO - SipB2BCallSteps - SipB2BCallSteps.java 186 TEST: Not yet determined
INFO - SipB2BCallSteps - SipB2BCallSteps.java 190 TEST: Terminated Dialog
...

Should SipUnit be closing the dialog in this scenario? If so how can I otherwise test for the response.

Cheers

I just found this function:
sipCallB.getDialog().terminateOnBye(false);

Seems to have changed the outcome of the dialog closure. Need to test further tomorrow.

Hi Hojo,

Yes, SipUnit sits on top of JUnit and JAIN-SIP 1.2. There is alot you can do with the JAIN-SIP classes. The javadocs are here:
https://developer.opencloud.com/devportal/devportal/apis/jainsip/1.2/docs/index.html

FYI, the SipUnit project has moved to this URL:
https://code.google.com/p/commtesting/
Questions/issues should be posted over there.
Have fun.
Kind regards,
Becky
