First off, let me say that this question also involves Cisco ASA's and Site-to-Site VPN, so if I'm posting in the wrong area, please let me know.
We are currently in the testing phase, (as this is a new topology configuration away from our current network model). We have set up a S2S VPN Tunnel between our corporate office and a small remote office, each site having a Cisco ASA 5505, (8.x). As I said earlier, the current remote site is a test site.
NOTE: This will eventually be put in place at a new remote site that will be a new acquisition for our company.
Currently we have the S2S Tunnel up and functioning, and both LAN's on each side of the tunnel can see each other. We have Cisco Call Manager 9.1 at our Corporate office. Furthermore, we also have the VoIP phone at the remote test site working properly; (Cisco 7942G).
My question(s), moving forward, are these:
With a POTS line(s) coming into the remote site, how do we accomplish getting the remote site's external phone number with the current carrier, (not ours), routed into the ASA and furthermore into our phone system at our corporate office so that we can route the calls internally with UCM? As I mentioned earler, this is going to eventually be a new acquisition, so that company, as it stands today, pays for this POTS line with a carrier other than ours.
Is this as simple as getting their carrier, (of the remote site), to route the 10 digit number to one of our Corporate owned DID's, which we would then be able to manipulate within UCM to route calls appropriately?
If I've managed to leave out too many details or have confused anyone, please let me know and I'll try to better clarify. Thanks.
