Dialing extensions containing *# at another PBX


The following howto exactly describes my setup: voip-info.org/wiki/view/Alcatel+4400+via+PRI.

For billing reasons, I can set at phones connected to the Alcatel pbx, an account code, before dialing a phone number:

Unfortunetly when I’m dialing an account code with asterisk I get a meaningless “hangup” at the cli.

Does asterisk have a problem with dialing extensions containing *# at another PBX? Is there a way to fix this?

Thank you in advanced for your help,


I think it coluld be, because in the default configuration Asterisk 1.4 use # for unattended transfers and * for hangup, so check the section featuremap in features.conf to see if/what this dtmfs are used for.

This would be default behaviour for an Agent. You can disable it in agents.conf.

You’re right, by default asterisk uses # for blind transfers and * for disconnecting.

After changing the values to #1 and *1 and a restart of the asterisk daemon, the issue still occurs:

    -- Executing [0*#20001234567890@test:1] Dial("SIP/9010-08bcdf00", "Zap/g1/*#20001234567890") in new stack
    -- Requested transfer capability: 0x00 - SPEECH
    -- Called g1/*#20001234567890
    -- Zap/1-1 is proceeding passing it to SIP/9010-08bcdf00
    -- Channel 0/1, span 1 got hangup, cause 1
    -- Hungup 'Zap/1-1'
  == Everyone is busy/congested at this time (1:0/0/1)
  == Auto fallthrough, channel 'SIP/9010-08bcdf00' status is 'CHANUNAVAIL'

I do not log in with an agent to make these calls, but i changed


in agents.conf anyway and there’s no diffrence.

Anyone an idea?
