Voicemail service

Hi All,

I have configured voicemail service for two voip accounts in my asterisk, and after configuring when I call to those lines, phones lines does not ring at all and gets forwarded directly to voicemail. Can some one help me to make phone line ring for 32 seconds and if not answered , call gets forwarded to voiceamail. Once Voicemail id deposited Asteroisk should send a NOTIFY message…
below setting has been done in asterisk

voicemail.conf 
----------------------------
"att26.com,,|tz=central|attach=yes|saycid=yes|dialout=fromvm|callback=fromvm|review=yes|operator=yes|envelope=yes|moveheard=yes|sayduration=yes|saydurationm=1
extension.conf"
--------------------------
exten => 2610,1,Dial(SIP/default,30)
exten => 2610,n,VoiceMail(2610@default,u

I assume you have default as the section name for your phone, in sip.conf. If so, you will need to provide the logs. Please mark them as preformatted text, on the forum.
