Hi Matthew and all , I am still trying to find the problem about SS7 signaling route. Now I am using SS7 protocol analyzer to check further my problem. my scenario: Signaling (16): Asterisk (PC 100) <-> MGW (PC 1001) <-> MSS (PC 1000) Circuit (1-15, 17,31): Asterisk (PC 100) <-> MSS (PC 1000) Asterisk's config in zapata.conf: pointcode = 100 adjpointcode = 1001 defaultdpc = 1000 MSS and MGW have configured routing correctly to see Asterisk (PC 100). I have seen STLM between PC 100 and PC 1000, but CGR from PC 100 to PC 1001 have no response back. I guess it's some problem with routing. I am in the stage to link up MTP3 between PC 1000 and PC 100. No successful ISUP messages yet in my scenario. Because I am really new to SS7, hard for me now to describe/identify the problem. Can you describe a typical flow for both MTP3 and ISUP layers? Any suggestions to me to identify my problem? thanks for help! cheers, /eric ================================================ > > As Joseph mentioned, the defaultdpc is where your ISUP traffic will be > sent.
