[Asterisk-doc] a few lines

[Randy Resnick]

Nothing earth shaking here but

1) Can someone please add that if the voicemail box is not in the 
default context a slight variant on the syntax is required:

Message Waiting Indication

SIP phones that support a message waiting indicator (such as a stuttered 
dial tone or a flashing light) can be associated with a voicemail box. 
In /etc/asterisk/sip.conf, just add a line like

		mailbox=1234
		

You can associate more than one mailbox with a SIP phone for a message 
waiting indication by separating the voice mail box numbers with commas:

		mailbox=1234,9999
		
***ADD***: If a mailbox to be checked is not in the default conext in 
voicemail.conf you must explicity provide the context as in
		mailbox=1000,2000@smokers,2001@drinkers

where mailbow 1000 is in defaul, 2000 is in a context called smokers and 
2001 is in the context called drinkers.

2)  I'm ready to write a quick non-commercial paragraph or two on the 
Budgetone phones for use with asterisk if no one else is doing it. I 
have a BT101 and 102 and find them adequate for soho and home use, 
although analog phones connected to a TDM400 are infinitely superior for 
the soho business pbx.
