[Asterisk-Users] Problem win Unicall

[Carlos Chavez]

     I am having a strange problem with an asterisk servier using R2 Unicall
in Mexico.  Most calls go through fine but some of them give me an error like
this:

    -- Executing Dial("SIP/86-db41", "Unicall/g2/014448343600") in new stack
    -- Called g2/014448343600

event Dialing

event Protocol failure
    -- Unicall/2 protocol error. Cause 32769

forward voice
    -- Hungup 'UniCall/2-1'
  == Everyone is busy/congested at this time (1:0/0/1)

     This particular call is national long distance.  But I have seen the
problem with some local numbers.  I even had a problem dialing a company in
the same city, their main numbers gave this error but their fax number went
through without problem.

     I am using Asterisk 1.2.4 (upgraded from 1.2.3 this morning), spandsp
.21, unicall 0.0.3.  Any ideas?  I am using a TE110P card with Zaptel 1.2.3
with 10 channels from Telmex.
