Have a branch cabinet CXII with a paging system providing dialtone and expecting dtmf digits to choose a zone connect to loop start port 1. From a set connected to the local cabinet I can dial the trunk access code plus the trunk ID and the dialtone is returned and I can pass dtmf and all is well. The issue lies with doing this from another MiVB in the cluster. I can dial the element ID plus trunk access code plus ID and the correct dial tone is returned but dtmf does not seem to pass.
Anyone have any thoughts? Is there something with COS on the the direct IP route between elements?
For what its worth - calls between extensions connected to each system seem to pass the dtmf to my ear when on a normal call.
