Fix a problem with packet-to-packet bridging and DTMF mode translation. P2P

Browse Source 
bridging can only be used when the DTMF modes don't match if the core is
monitoring DTMF in both directions.  Then, the core will handle the translation.
Otherwise, this bridging method can not be used.
(issue #8936)
