[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
