fix(audio): stuck unmute due to borked callerId(Num)

Browse Source 
FreeSWITCH incorrectly generates callerNum headers in its ESL events
when specific, special characters are in place. e.g.:
w_etc_0-bbbID-User;Semi (notice the semicolon) will be generated by
FS as w_etc_0-bbbID-User (everything after the semicolon is ignored).
This breaks callerId comparision for session matching in a few places -
one of the is the unmute/unhold toggle control.

Compare callerNum as prefixes instead of exact strings to match those
scenarios.
This is a temporary fix; we should review callerNum generation in the
future (use Caller-Id-Name in FSESL), as well as stop relying on it
for session matching (use UUIDs and/or client session numbers instead).
Both of these are more involved changes, though.
