Good day I have a setup using a 4 port Digium Card,Asterisk 1.6.2.15,libss7-1.0.2,dahdi-linux-complete-2.4.0 My dahdi config looks like so : # Span 2: TE4/0/2 "T4XXP (PCI) Card 0 Span 2" HDB3/CCS/CRC4 span=2,2,0,ccs,hdb3 # termtype: te bchan=32-46,48-62 mtp2=47 #echocanceller=mg2,32-46,48-62 (the other spans are disabled) [channels] signaling=ss7 ;this is ss7 signaling ss7type=itu ;using the ITU variant ;ss7_called_nai=dynamic ;NAI for outgoing calls ;ss7_calling_nai=dynamic ;NAI for incoming calls ss7_internationalprefix= ;international prefix value for incoming calls ss7_nationalprefix= ;national prefix value for incoming calls ss7_subscriberprefix= ;subscriber prefix value for incoming calls ss7_unknownprefix= ;unknown prefix value for incoming calls ss7_explicitacm=yes ss7_explictacm=yes group=1 context=ss7 linkset=1 pointcode=720 ;the point code for this system...aka SPC adjpointcode=1832 ;the point code for the system that we are signaling to... aka APC defaultdpc=1368 ;the point code for the system that the CICs will be negotiated with...aka DPC networkindicator=national_spare ;NI value for MTP3 cicbeginswith=32 ;the starting value of the CICs channel=32-46 cicbeginswith=48 channel=48-62 ;the channels that are CICs sigchan=47 ;the signaling channel The Links come up. It seems fine. When I make a call to the link I get the following on the asterisk CLI Unhandled optional parameter 0x8 'Optional forward call indicator' [0x0 ] Unhandled optional parameter 0x31 'Propagation Delay Counter' [0x0 0x5a ] Unhandled optional parameter 0x3f 'Location Number' [0x84 0x93 0x72 0x38 0x0 0x10 0x7 0x0 0x0 0x0 ] Unhandled optional parameter 0x39 'Parameter Compatibility Information' [0x31 0xd0 0x3f 0xc0 ] [Dec 10 19:36:12] WARNING[3627]: chan_dahdi.c:11850 ss7_linkset: IAM on unconfigured CIC 6 [Dec 10 19:36:13] WARNING[3627]: chan_dahdi.c:12142 ss7_linkset: RLC on unconfigured CIC 6 It doesnt seem to trigger even the extentions. I cant get the Chan_ss7 to work, as My DPC and APC are different(if im mistaken please assist, I would gladly try chan_ss7) I just need to get the incoming calls working urgently. Any assistance will be greatly appreciated. Kind regards Edrich de Lange
