Re: CRBT

Hi

CRBT is same one Switch and have more Database.

When A sucriber call to B subcriber. MSC A will ask HLR about SS_code. If B is RBT subcriber. The flat is on. After MSC A recieved SS_code from HLR. MSC A will make call to RBT systems, same normal call.
  - MSC A send IAM to RBT. RBT will check phone number and check info of this number(song code).
  - if checking's okie. RBT will send back to MSC ACM.
  - RBT send to MSC ANM and start playing song.
  - When B hook on or no answer, MSC will send REL to RBT. and finish one RBT Call.
If need more detail, send me your email. I will send documnet to you.

Re: CRBT

There is two kind of triggering the CRBT profile. One is using IN solution and the other one is using a pacth on the MSC. 
 
Both solution is only to ask the CRBT platform if the subscriber have the profile of CRBT active and if it's true, then send the calling leg to the CRBT tone server to play the song while the MSC generate a second call leg towards the called party. 
 
What MSC vendor are you using ? Ask them if they can handle the CRBT pacth or if they implement the CRBT solution trough IN services.

About CRBT - Who establises Voice path

Hi ,
What ever discussed in the above blog... I have one doubt.

MSC ---- CRBT System
IAM -->
<-- ACM
<-- ANM
VOICE PATH ESTABLISHED
REL--->
<--- RLC

Now who is establishing voice path??
1. MSC
2. CRBT System

NOTE:- Song will be played by CRBT system, but who will open the voicepath after ANM???

Reply :About CRBT - Who establises Voice path

Hi,

Please note that only B party can establish voice path, so in CRBT(SRBT/PRBT/RBT) call flow CRBT system will establish voice path.
Please let me know if you have any other doubt ..?

MSC is a Switch right, just

MSC is a Switch right, just like in OSI model, Switch,Router etc.

And CRBT(Caller Ring back tone) system is a server which is handling calls through E1s, Its true that we are using some time of cards in server to handle those E1s, but I don't think CRBT system only opening the voice path. Do you have any kind of ISUP/SS7 doc, where I can get a clear view about this doubt.

Hi Signh

Could you clear your question? as i understand, when B hook ON, MSC will send REL to CRBT for closing this voice channel. This is feature of MSC.

CRBT Call flow

Is in one leg MSC sends IAM to CRBT and in other leg Paging message towards Subsriber in case of home PLMN and in case of out roamer MSC will send IAM to GMSC and as sson as ANM message will come.MSC will send release to the CRBT. Is this flow?

sreehari
Hello

Yes.!! in case the subscriber is local, 2 different call legs will be established. One for CRBT and the other for actual terminator. Once the terminator answers, MSC send ISUP REL message to CRBT.

For a roaming case i'm not clear with your query. But, whatever, once the ISUP ANM arrives from the subscriber an MSC sends an ISUP REL message to CRBT.
