[asterisk-users] Asterisk + zap + sangoma A104D - how to setup call using particular timeslot

[Marcin J. Kowalczyk]

Hi all,

 I need to setup call using particular timeslot on one of E1's. I've 
looked into 
http://www.voip-info.org/wiki/index.php?page=Asterisk+Zap+channels and 
it says that:

exten => TestTrakt,1,Dial(ZAP/1-2/517255333)
exten => TestTrakt,2,hangup

should work and force call setup via span 1 (port 1) but when I try 
setup call rasterisk says:

    -- Executing [TestTrakt at na-miasto:1] Dial("SIP/sempron-b2ae1918", 
"ZAP/1-2/517255333") in new stack
[Jun 19 21:22:20] WARNING[23814]: chan_zap.c:7966 zt_request: Unknown 
option '-' in '1-2/517255333'
    -- Requested transfer capability: 0x00 - SPEECH
    -- Called 1-2/517255333
    -- Hungup 'Zap/1-1'
  == Spawn extension (na-miasto, TestTrakt, 1) exited non-zero on 
'SIP/sempron-b2ae1918'


any idea how to force Asterisk to push call via particular timeslot?

Regards,
Marcin
