Hi,

SIP phone receives the following in the NOTIFY message.

NOTIFY sip:[EMAIL PROTECTED] <[EMAIL PROTECTED]> SIP/2.0
Via: SIP/2.0/TCP 10.10.225.196:2942;branch=
z9hG4bK10316335372635889177391012394138
---
Messages-Waiting: yes
Message-Account: sip:[EMAIL PROTECTED] <[EMAIL PROTECTED]>
Voice-Message: 0/0 (0/0)
Fax-Message: 0/0 (0/0)

I would like to know whether this message is valid since "Message-Waiting"
is set to yes but there are zero messages.

If the message is invalid, what should be the response from SIP phone?

SIP phone has subscribed for MWI indication.

Thanks,
Jagan
