Hi,
I've got ser working great over here, but I cannot find out how I can play a message before forwarding the call. Like this:
- Person A calls person B via the SER proxy - SER proxy forwards to mediaserver - Mediaserver plays a message (like 'this call is free of cost') - Mediaserver hangs up - SER proxy forwards the call to person B - Person A and person B can talk to each other now..
Is this possible ?
Thanks,
Leon de Rooij leon@scarlet-internet.nl
yes, this is possible, but not only with ser - you need a b2bua to do all this. bogdan

Hmm.. thanks, but does that mean that the entire RTP connection will go through that b2bua (also the call from a to b) ?

emmm,
I thought that media goes through b2bua. That's how b2bua can terminate the call. Ser should be able to handle signaling by adding it in the signaling path, right? I am a little bit confused.
Thanks, Richard

no.b2bua is a signaling entity -- it does not have to see a single RTP packet.

not really. b2bua is a pure signaling entity -- it keeps UAS dialog state and UAC dialog state. Additionaly a b2bua may change SDP in a way which forces media to visit some specific host but that's a special b2bua species. With knowledge of call state, a b2bua is able to send BYE to all call parties -- that's how it terminates a call.

Thanks Jiri, to make sure I understand, two more questions...
For a prepaid service, e.g. announcing 'you only have one minute left', b2bua should be in the media path, right?
If call accounting is enabled in ser, it is possible for ser to keep track the state and make it a b2bua by adding a new module, right?

You can use the sems and the lastest ivr module.
When a call comes in, it calls a perl or python script which can play a message and use 'REFER' to redirect the call to b. So the media won't go through sems for the real call.

Great.. I just got it working by forwarding the call to an asterisk box where the message is played, and after that forwarded from asterisk to the final destination (with the final rtp connection not going through asterisk). It works, but I would prefer using sems as you suggest. Thanks a lot :)

No. By definition, proxy server does not keep call state. you would need a B2BUA.
