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 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
		

If a mailbox to be checked is not in the default context in voicemail.conf you must explicitly provide the context as in


		mailbox=1000,2000@smokers,2001@drinkers
		
Where mailbox 1000 is in default, 2000 is in a voicemail.conf context called smokers and 2001 is in the context called drinkers.
