[Serusers] ser+asterisk+voicemail - sr-users

29 Mar 2005


      hi all
configuration:
inalp gw (pstn) ------> ser ------> asterisk (only voicemail)
the following problems occur:
1) ser forwards the call to asterisk (if the user is in the voicemail
group) if the client does not answer after 30 sec.
from sip to sip is working.
but if a call comes from the pstn to a sip client, the client rings and
hangs up after 30 sec. ser then forwards it to the asterisk, but the pstn
call keeps on ringing and no voicemail is to hear.
ser writes the following error

2) if ua1 call ua2 (and ua2 is in the voicemail group) and ua1 hangs up 
ser forwards to asterisk and the voicemail is run in the background,
but instead the call should be cancelled and not forwarded to the voicemail
does anyone know about these problems?
