[asterisk-users] Recommendation for extension mapping on inbound T1 line

[Mitch Claborn]

Converting this customer from a MiTel system to asterisk. Discovered 
that the inbound calls from the T1 are going to extension 366.  (This 
was mapped in the MiTel for some arcane purpose.)  The dial plan I am 
currently using is shown below.  When loading the dial plan, I get this 
warning:

  WARNING[5004]: pbx_config.c:1561 pbx_load_config: The use of '_.' for 
an extension is strongly discouraged and can have unexpected behavior.  
Please use '_X.' instead at line 331 of extensions.conf

Question: Do I need to worry about this warning?

I'm a little leery of just using 366 in the dialplan, since the company 
we are dealing with is a little flaky.

exten =>_.,1,NoOp(pstn call from ${CALLERID(all)} exten=${EXTEN})
   same =>n,Goto(MainMenu,s,1)
