I have to configure a remote site with h323 and with cme in srst mode when the WAN fails. What I am trying to understand is that if the router goes into srst mode how will calls reach the remote site from external if there is no DID. I was actually thinking about having a connection plar to an extension internal but with h323 all voice ports will be set to the AA at the head office as 7000. Any ideas of what can be done in an instance like this. I cant seem to think of anything that will work.
