asterisk users - Feb 2005 - Broadvoice international dialling question

I'd be grateful if someone could point me in the right direction.  

 

I have a Broadvoice trunk attached to Asterisk which I use for frequent
calls to the UK using the following in extensions.conf

 

exten => _0[1-68].,1,Ringing

exten => _0[1-68].,2,Dial(SIP/BV/01144${EXTEN:1})

exten => _0[1-68].,3,Hangup

 

The caller hears immediate ringing, though it seems that Broadvoice takes a
long time to make the international connection and sometimes fails
altogether

 

-- Executing Ringing("SIP/100-4ad1", "") in new stack 

-- Executing Dial("SIP/100-4ad1", "SIP/BV/011441234654321")
in new stack

-- Called BV/011441234654321

-- SIP/BV-9dfd is ringing

-- SIP/BV-9dfd answered SIP/100-4ad1

 

            or

 

-- Executing Ringing("SIP/100-3894", "") in new stack

-- Executing Dial("SIP/100-3894", "SIP/BV/011441234654321")
in new stack

-- Called BV/011441234654321

-- Got SIP response 408 "Request Timeout" back from 147.135.0.128

== No one is available to answer at this time

-- Executing Hangup("SIP/100-3894", "") in new stack

 

147.135.0.128 is Broadvoice's server and I understand that I need to take
the request timeout issue up with them, but can anyone suggest how I might
configure Asterisk to perform an unattended transfer rather than giving
misleading ring-tones even when the destination phone is not ringing?  I
feel that it gives a clearer indication of call progress to have a long
silence after dialing, followed by the ring (or congestion tone), rather
than the current immediate ringing.

 

I have searched for extensions.conf examples of this, but haven't come
across any which work for me.

 

Many thanks,

 

            Malcolm

This is because you've told Asterisk to play a ringing sound before it has
even attempted to place the call with BV. Take out your Ringing line and
that behavior should stop.
