[asterisk-users] Dial timeout to cell phones

[Steve Repo]

Hello,

I'm new to asterisk and i'm having a really good time configuring it.

I'd like to VoIP-to-PSTN call my SIP number (${MYSIP}) first and then
my cell phone (123456) and then finally to my voicemail.

Here's my dialplan.

exten => s,1,Answer()
exten => s,n,Dial(${MYSIP},20)
exten => s,n,Dial(Zap/g0/123456,10)
exten => s,n,Voicemail(${MYSIP}@default)
exten => s,n,Hangup()

When I receive calls, my IP phone (SIP) rings for 20 seconds as
expected. However, asterisk does not terminate calls to my cell phone
after 10 seconds and keeps ringing.

The call to my cell phone is then answered by cell phone voicemail
instead of asterisk voicemail.

Any ideas how to go about this?

Thanks!
Steve
