Hello All,I have a situation where a service provider wants to connect two Cisco CallManager clusters to a SIP Trunking provider. One cluster is running 4.2 and the other is running 6.x. They have suggested we purchase an Acme Session Border Contro...
I have been looking into mVPN and have a question that I couldn't find addressed on CCO. Does Cisco's implementation of MPLS (mVPN) allow the CE Router to send Multicast NLRI (through mBGP) to the PE router so to influence ONLY the multicast RPF che...
Hello,I am trying to find out if a CallManager 4.x system can communicate to an IP Telephony Service Provider over SIP to their Sessions Border Controller. From what it looks like, I will need an IP2IP gateway to talk H323 to the CCM and SIP to the ...
Hello all,I have a situation where I am trying to connect a CME 3.2 system, running on a 2821, to Global Crossing' s Local Dial and Outbound Dial service. They are using an Acme Session Border Controller, which at this point, does not support "SIP R...

Thanks for the reply! Judging by your descriptions, you tested with SIP softphones. Did you test from CallManager to and ITSP's Session Border controller as well?Thanks again,Darin
Wayne,I did get some features to work, however, there were serveral querks that ultimately convinced me to stay away from the solution until it matures. In my scenario, I did not need a userid and pin as Global Crossing authenticates you by putting ...
I'm not going to use CBAC + FWSM's or PIX's. We have serveral sites that will be connected to an untrusted backbone at 100mb/s and I am trying to determine if CBAC on the MSFC will be able to support this. From my lab tests using harpoon (throughpu...
