Thanks, it is very nice to get some real questions :)

I'm now running in my bed, so I may be confused but I think that the spec tells 180s to extend life of transaction context (i.e., extend C-timer). I don't necessarily like it, and I think it was just a too quick result of a discussion which the sip mailing list wanted to complete (roughly during bis-07 time).

I need to review what SER actually does. Not extending the transaction lifetime through 18x should be at least a config option.

Hi!

I tried voicemail with redirect to the vm-proxy if the user doesn't pick up the phone after 10 seconds. It works fine if I call a kphone user, but not with SIPPS users. SIPPS sends a 180 Ringing every five seconds which probably resets the timer - if I choose timer intervalls shorter than 5 seconds it also works with SIPPS.

Is this a bug?

tried with ser: 0.8.12dev-t14 0.8.11rc1 0.8.11-r1
