PSTN Breakout over Meshed VPN

HI,

I've set up a meshed VPN using the CCA, connecting a device in London (UC560) and one in Frankfurt (UC540).

Each device have their own ISDN connectivity (BRI in Frankfurt, PRI in London)

Both are working fine for PSTN calls, and allso calls between offices using the meshed VPN work well.

What I need to do now is allow staff in London to dial German numbers through the Frankfurt system, and vice-versa, so avoiding international call charges.

Can anyone advise firstly, is this possible with the UC range?

Secondly, if it can be done via CCA3?

Thirdly, if it can only be done via CLI what dial-peer modifications would be required, or is there another command for allowing VOIP to PSTN routing?

I have included the dial-peers and associated translation profiles and rules that allow Frankfurt to call London. We use 4 to indicate a site-to-site call, then 1 to identify London and 2 to identify Frankfurt.

I tried modifying these to destination-pattern 419.T as a test and this does allow the call from Frankfurt to reach the London device, but it does not go from there to the PSTN.

In Frankfurt***********
