[SR-Users] any one use multicast for paging ?

[Ming Liu]

  Hi Daniel,

 

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

 

   INVITE
sip:9621 at 10.150.152.102:5060;transport=udp;maddr=10.150.152.102
SIP/2.0^M

    Via: SIP/2.0/UDP

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.
