[Serusers] t_relay

hi all, can a t_relay that got no answer be forwarded to a voicemail? The scenario is the following: i have a 'call group' sip-user (implemented in mysql database) that call t_relay when an INVITE is rcvd. As consequence of the t_relay the mentioned INVITE is forwarded to different destinations, and when one destination answers the call a CANCEL is sent to other destinations. The problem exists if no destination attends the call. How can I tell ser to forward the call to voicemail if no user belonging to group 'call group' answers the call? thanks!!! victor -- Victor Pascual Ávila mail: victor.pascual.avila(a)gmail.com sip: 17476374121(a)proxy01.sipphone.com linux user: 224443
