I'm trying to finalize the configuration of a UC540 connected via VPN to a remote PBX...
The VPN circuit terminates on a Cisco ASA 5510 and Legacy PBX have 2 ISDN port connected to a Patton SN4554 gw; now, I want to find the best configuration, avoiding if possible any problems with CCA!!! Indeed, already for the VPN I have worked with the CLI :-(
I have not checked whether I can work on gw as a server and connect the UC500 with a sip trunk or if I have to follow another path; however, ultimately I would like some advice, ideas, configuration to simplify things and to work the UC500 as a satellite of the legacy PBX. The essential goals are to divert some external calls to the remote site and manage the possible transfers / calls between offices.
There would be several things to add but for now I will stop here!
