Hello,
Thanks for the reply. I'm using the bundled/skeleton configurations just to test with a few modifications (adding the actual voicemail server) however even with the skeleton configurations, when the call goes unanswered, and the call forks to voicemail, the INVITE packet is sent first, followed by the CANCEL to endpoint 2. The following is a SIP trace of what I'm seeing:

Hello,
default kamailio.cfg has a skeleton for doing serial forking to a voicemail server. Follow the token WITH_VOICEMAIL to discover the related snippets -- this can be a starting point to implement it in your config.
Cheers, Daniel

Hi James,
The difference you are describing is between serial and parallel forking. You clearly want the former. There are a variety of ways to achieve that, and the answer will depend on the code path taken to route to your voicemail server.

Hello,
Is there a way to change the transaction order when a failure fork occurs -- to explain, endpoint 1 calls endpoint 2. Call towards endpoint 2 goes unanswered, and so the call forks to voicemail, I see that an INVITE is sent towards my voicemail server first, followed by a CANCEL towards the endpoint; can I send the CANCEL first to the endpoint and then INVITE towards my voicemail server. I'm essentially using the bundled/sample configurations for testing.
Thank you.__________________________________________________________ Kamailio - Users Mailing List - Non Commercial Discussions To unsubscribe send an email to sr-users-leave@lists.kamailio.org Important: keep the mailing list in the recipients, do not reply only to the sender!
