Hi, The ongoing discussion, suggests that SGP can never receive a DAVA message. However, consider the scenario of two separate SS7 networks connected to each other via two SGs. In such a case won't the two SGs be sending DUNA/DAVA messages to each other? rgds Saurabh Hi Brian, Yes, you're right BR, Santi. -----Original Message----- From: Brian F. G.

DAVA only relates to remote SCCP and SCCP subsystems. For which SCCP subsystems the SG sends SSA is determined by the routing key associated with the AS for which the ASP has activated and the state of other ASPs in the AS. > > --brian > > > Salil Agrawal wrote: (Thu, 25 May 2006 10:14:18) > > Hi, > > > > In case of SUA, Can ASP sends DAVA messages to SGP after receiving > > Asp Active Ack message.
