REFER expectations

[sfgeorge]

• Add support for expecting and accepting a REFER message.

Ok, to answer my own question, it looks like you're using when responding with a 200 to a REFER, in which case you do not want rrs.

Also, would you mind adding some tests to cover this new functionality?

[bklang]

@sfgeorge, when you get a chance: In addition to the tests, I know that @vindir identified some changes to the REFER flow that need to be made in order for it to work successfully. Would the two of you get together and update this PR to include the corrected messages?

[bklang]

@sfgeorge If you would still like this merged, would you update it so it can be merged? Also, I believe @vindir had a functional change to make to the generated SIPp instructions, in light of our testing with your infrastructure.

[benlangfeld]

This should probably wait until #34 is merged in a couple of hours.

[benlangfeld]

Ok, #34 was merged. Please ensure this PR complies with the standards of testing and documentation now in effect on Scenario.

Pssst... just pinging the project :)

[bklang]

I think there are two outstanding items on this:

• Fix the generated XML for REFER scenarios (this one contains a bug if I recall correctly)
• Add/update specs to handle the new methods

[sfgeorge]

Agreed! Regarding point 1, @vindir Can you share any insight you have with problems you had with the REFER dialogue I constructed?

[bklang]

@sfgeorge By any chance, do you have SIPp scenarios containing a REFER that you can compare to this PR? Can you either confirm that the REFER this code generates is correct, or suggest a change?

[sfgeorge]

Howdy! Yes, I can sure give an example exchange from Asterisk 1.8 that matches this exchange. Would you recommend any other systems to compare against?

[bklang]

I'll take whatever examples you've got, but Asterisk 1.8 is a good start.

[benlangfeld]

@sfgeorge Do you have those examples? Might you be able to rebase this PR so we can get it in to the next version?

[sfgeorge]

Eek, sorry for the delay. Happy Holidays, Happy New Year and Happy Saint Patrick's Day! 🍀 😄

I can rebase this weekend if that works.

What's the best format for an example? I can send you pcap if that would suffice.

[benlangfeld]

A pcap would be fine :)

Hello,
i'm interested to get this feature up and running.
Does an scripting example exist to save me some time during testing ?

[sfgeorge]

Hi @pk1057 my foul, I will try to update this PR and share for your and everyone's benefit. Thank you for the reminder! 🎗

[pk1057]
