Hi Daniel,
The INVITE contains maddr=10.150.152.102 and hope server can do multicasting to several phones to achieve paging functionality:

Hi,
Need help on paging case.
The via header has maddr field contains multicast ip address, how does this configure ?
can you paste here such INVITE? I am not really understanding from your message what exactly you are looking for, maybe you can give a bit more details about what you expect to happen.
Cheers,
Daniel
And how does sip proxy server react ?
Advice would be appreciated.
