I have a central node with a 1760-V, in other two remote sites have 1751-V and 1750-V.
Problem is after I access the extension in central node I receive tone, then dial the remote pot, it takes around 15 to 20 seconds to receive the ringback.
I tried to configure interdigit option in voice ports, handle it in 5, 2 and 0 values but didn´t have a good result.
Is there another parameter I could handle to improve the response time?
I am using version c1700-sv8y-mz.1222-8.T5.bin in central node.
