I have a test plateforme with to PSTN provider and with only one 2821 voice gateway.

I'd like to simulate the PSTN by linking the 2 E1 controller on the VWIC-2MFT-T1/E1 of my gateway using to E1 cross-cable.

At the beginnig I did in MGCP but it didn't work probably due to CCM loop avoidance mechanism, then I did in H323 but it still not working.

Do you have any idea if it is possible or not?

I attached to conf if you want to have a look.

PS:all test numbers start with 69XXX ,I created a route pattern "*.69XXX" to use the H323 gawteway to force call to go through the GW

For starters, try making the following changes:

dial-peer voice 100

incoming called-number .


dial-peer voice 1

incoming called-number .

destination-pattern .T
