We are trying to connect an SRG50 to a 1000M. The idea is that we will use some of the sets and connect them to the CCM 6.0 we have on the PBX. All the sets on the SRG will have local inbound and outbound DID. In a SIP setup, the sets would not recognize the local inbound and outbound PRI, all calls routed out through the PBX. We reverted to H323 and the inbound started working properly but the outbound had a 12 second delay before any ringing could be heard. thoughts?
