[Serusers] fr_inv_timer problem when using SIPPS

[Klaus Darilion]

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

regards,
Klaus
