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

Did you check so see if the pri is up?
Also, make sure wanpipe & dahdi is setup correctly.

You're saying that calls that come from the master to the slave end up in context from-pstn (on the slave), but calls from the slave to the master ALSO end up in from-pstn (on the master). Seems like one of them should be "from-internal" or the like. I'm sure some of your problem emanate from these settings.> satish-desktop*CLI> > [Mar 25 15:40:19] WARNING[4519]: app_dial.c:2039 dial_exec_full: Unable > to create channel of type 'DAHDI' (cause 34 - Circuit/channel > congestion)Check the other side for error messages.> [Mar 25 15:40:19] WARNING[4519]: acl.c:698 ast_ouraddrfor: > Cannot connect [Mar 25 15:40:19] WARNING[4519]: chan_sip.c:3115 > __sip_xmit: sip_xmit of 0x14249d0 (len 763) to 0.0.29.103:5060 returned > -1: Invalid argument [Mar 25 15:40:19] WARNING[4371]: chan_sip.c:3115 > __sip_xmit: sip_xmit of 0x14249d0 (len 763) to 0.0.29.103:5060 returned > -1: Invalid argumentThis problem is due to a misconfiguration. Asterisk cannot handle the local network being addressed as the 0.0.0.0 network. You need to use the full local address. -- Tilghman
