[cisco-voip] Single Number Reach

Do your users really want to dial into an IVR to change their settings access? Most users are cool with the mobility button on their phone and ccmuser access.

Hi,

I am planning to implement SNR, however after reading docs I am left with more questions !

My PSTN access is using SIP trunks to SP, with the gateways being CUBEs configured as SIP trunks to CUCM. One of the caveats I read is that "Only H.323 VoIP gateways are supported for Mobile Voice Access", I am really keen to use this specific feature but wondered what options I have. I know I can probably configure the CUBEs to be H.323 GWs to the CUCM and possibly do H232toSIP on the CUBE. For various reasons even if this would work I want to avoid doing that...

It does mention H.323 GW can be added and use to 'hairpin'; I am not quite clear on the topology here, can someone offer some advice?

I though it might be adding an additional H323 GW standalone, whereby calls come into the CUBE from SP SIP trunks are forwarded over the SIP truanks to CUCM which then routes on to the H322 GW to accsss the Mobile Voice access IVR, whcih then hairpins traffic back to CUCM... or am I way off the mark?

My searches suggest not many docs on this and admin guide is somewhat vague..

Any help greatly appreciated...
