[Asterisk-Users] Help with Dial multiple channels simultanously

[Kib Eki]

Hi,

the following from extension.conf does not work correctly:

exten => 301, 1, Dial(SIP/455&SIP/456, 15)

 That is the console output:
    -- Executing Dial("mISDN/1/105", "SIP/455&SIP/456&SIP/456| 10") in 
new stack
    -- Called 455
    -- Called 456
    -- SIP/455-46a8 is ringing
  == Spawn extension (incoming, 301, 1) exited non-zero on 'mISDN/1/105'

As you can see only the extension 455 is dialed.

What is wrong with my configuration?

Thank you very much,
Kib
