Did you check so see if the pri is up? Also, make sure wanpipe & dahdi is setup correctly.  From: asterisk-users-bounces at lists.digium.com [mailto:asterisk-users-bounces at lists.digium.com] On Behalf Of satish patel

Subject: [asterisk-users] Back-to-back asterisk PRI issue Following is my scenario to connect back to back PRI of two asterisk server. PRI cards are Sangoma A102D 

[Asterisk1]------------[PRI]-Cross Cable---------[Asterisk2] 

Asterisk1

; Span 1 (MASTER)
switchtype = national ; commonly referred to as NI2
context = from-pstn
group = 0,24
echocancel = yes
signalling = pri_net
channel => 1-23


Asterisk2

; Span 1
switchtype = national ; commonly referred to as NI2
context = from-pstn
group = 0,24
echocancel = yes
signalling = pri_cpe
channel => 1-23



Following is my extensions.conf stuff on both machine (extension number could be change) 

[from-pstn]
exten => s,1,Answer()
        same => n,Playback(hello-world)
        same => n,Hangup()


[from-sip]
exten => _7XXX,1,Answer()
        same => n,Dial(SIP/${EXTEN})
        same => n,Hangup()

exten => 7527,1,Dial(DAHDI/G0/7527)



But i am getting following error when i am calling from A to B
