[Asterisk-Users] Asterisk Outbound Calling Warning: Unable To Forward Voice

When trying to make outbound calls I am getting the Warning: File 
app_dial.c line 313 (wait_for_answer) Unable to forward voice.

When making the call it attempts to dial (pounds are actually numbers 
but replaced to not show numbers we are dialing):

Executing Dial("Sip/donas-bd7b", Zap/g1/1##########") in new
stack
Called g1/1##########
Channel 1, span 1 got hangup
**Above warning message**
Hungup 'Zap/1-1'
No one is available to answer at this time
**Goes to Congestion()***
Spawn extension (csr_incoming, 91##########, 2) exited non-zero on 
'SIP/donas-bd7b'


Now, what happens is when the call is made it is busy right away not 
even dialing out...it seems to go to Congestion almost immediately.

The following is extensions.conf outbound_calls context which IS
included in the sip phones default context:

[outbound_calls]
ignorepat=9
exten => _91NXXNXXXXXX,1,Dial(${TRUNK}/${EXTEN:1})
exten => _91NXXNXXXXXX,3,Congestion


Answers to questions that may be asked:

1.  Trunk is defined as g1 in globals
2.  Group 1 channels are defined in zapata.conf
3.  Using T1/PRI
4.  Cisco 7960 w/SIP
5.  Using CVS from 2 weeks ago
6.  Already tried direct Zap (eg.Zap/15) instead of using TRUNK var



So, when calling out we get a busy signal...calling to internal 
extensions works fine.  Have tried almost everything and are beginning 
to wonder if there is something wrong with our carrier's config.

We tried running pri debug on the span and got the following which is 
hard to understand:

[Asterisk-Users] Asterisk Outbound Calling Warning: Unable To Forward Voice

Q931 DISCONNECT message maps the release cause in both directions. For
instance, the release cause is:

Cause: Temporary failure (41), class = Network Congestion (2)

Do you delete o replace part of SETUP message? Is very weird this part:
> ^M> Called Number (len=14) [ Ext: 1  TON: National Number (2)  NPI:
> ISDN/Telephony Numbering Plan (E.164/E.163) (1) '1##########'
> ^M^[[1;30;40m    -- ^[[0;37;40mCalled g1/1##########
Its according to your extensions Dial() configuration...
You are sendig National Number, such as Long Distance Call.

I assume that the release cause is sent to your by your provider.

Regards,

Gus
