how identify if multi-channels?

Posted:Mon 10 of Mar, 2008 (12:09 UTC)
usually, most phone supports now multiple lines.
for example, 200 calls 300 and then 100 calls 300 while first call holds.
issuing "show channels verbose", we can see 2 channels with same ext. 300.
if user of 300 presses hold button and turns into connection with 200,
HOW we can identify which one is we use transfer?
