Hello.
I am configuring the Asterisk gateway (SIP/PSTN). I have two quad span PRI cards (TE411p) installed there. The cards are detected correctly. zaptel module and wct4xxp module are loaded (modprobe -l zaptel; modprobe -l wct4xxp -> both pops up the module name). All 8 spans are configured. The command ztcfg -vvvvvv shows all 248 channels (E1 are used).
Spans in zaptel.conf :
span=1,0,0,ccs,hdb3,crc4
bchan=1-15
dchan=16
bchan=17-31
span=2,0,0,ccs,hdb3,crc4
bchan=32-46
dchan=47
bchan=48-62
span=3,0,0,ccs,hdb3,crc4

bchan=94-108

bchan=110-124

Groups in zapata.conf :
group = 1
channel => 1-15,17-31

group = 3
channel => 63-77,79-93

Dialing in extensions.conf :
exten => _X.,1,Dial(Zap/g1/${EXTEN},300,r)
exten => _X.,2,Dial(Zap/g2/${EXTEN},300,r)
exten => _X.,3,Dial(Zap/g3/${EXTEN},300,r)
exten => _X.,4,Dial(Zap/g4/${EXTEN},300,r)
exten => _X.,5,Dial(Zap/g5/${EXTEN},300,r)
exten => _X.,6,Dial(Zap/g6/${EXTEN},300,r)
exten => _X.,7,Dial(Zap/g7/${EXTEN},300,r)
exten => _X.,8,Dial(Zap/g8/${EXTEN},300,r)
;exten => _X.,2,Dial(Zap/g2/${EXTEN},300,r)
;exten => _X.,4,Dial(Zap/g3/${EXTEN},300)
;exten => _X.,5,Dial(Zap/g4/${EXTEN},300)
exten => _X.,9,Congestion
My problem is following. I cannot make more than 30 calls from IP to PSTN if just single PRI line is plugged into each quad span card (two PRI active together on the different cards). Separately I can utilise all 30 channels of each port but I cannot make them to perform together more then 30 calls (e.g. I cannot make 40 calls using just two PRI on two cards).
Please could you help me to solve this issue? I browsed the Wiki’s pages and other guides but did not found solution yet. I tried to put all channels to the same group but it was not working.
Thank you very much for your help.
Best regards
Dalibor
