[SIPForum-discussion] Help required

[Dawn Somen-NXDR43]

Hi!
 
I am a student studying SIP and PSTN interworking at Motorola. I tried
to find a answer to this query but couldn't yet.
Could you please help me with this one?
 
My query is as follows:
Usually it is so that we can subscribe with our service provider of the
cellular network for music (I mean if someone calls us he/she can hear
some song or music instead of the usual phone ringing) Could you please
tell me which device in the SIP network or PSTN network does this music
playing specifically and where exactly I can find more information on
this?
 
Thanks a tonne!
 
Regards,
Somen
