[Freeswitch-users] Newbie question: Executing Lua scripts for incoming calls, how concurrency is to be handled?

Hi Michael,

>> How are you physically connecting from FreeSWITCH to the PBX?

I connect this via E1 link - I have a Sangoma card installed on the FreeSWITCH machine.

With regards,
Sirish

To trigger SIP registrations you'd need the PBX to have a SIP client. I'm assuming this is possible, but maybe that's a false assumption. How are you physically connecting from FreeSWITCH to the PBX?

Hey Guys,

Would really appreciate if you could help me out here - isn't there a way to handle concurrent calls in the dial plan, especially when Lua scripts, accessing global variables, are executed on receiving calls?

Is mod_fifo the closest I could get to handle concurrency (as Michael has explained)? If yes, how do I trigger SIP registrations, especially working with a PBX which I don't have full control of?

With regards,
Sirish

Hi Michael,

Thanks for the reply.

>> You would need a SIP registration from the PBX to FreeSWITCH for each of the modem extensions
I am seen SIP clients such as X-Lite sending out the SIP registrations, but could you please clarify as to how this can be achieved in the PBX? The final production environment would be out in the customer's PBX, which I may not have complete control of..

>> What application are you building?
I may not be able to provide the details because of the NDA with customer, but what I am trying to achieve is, to replace an existing IVR with FreeSWITCH in an old existing setup of the customer - that's the reason why we continue working with dialup modems!

With regards,
Sirish

You don't have to have actual human agents for mod_fifo. You could define a user for each modem and then manually "log in" those "agents" on the command line using the fifo_member API command. Something like this:

fifo_member add fifo_name {fifo_member_wait=nowait}user/1234

Where 1234 is the user id of one of the modems. You would need a SIP registration from the PBX to FreeSWITCH for each of the modem extensions.

Having modems go through a VoIP system sounds a bit scary. What application are you building?

Hi William,

Thanks for the reply.

My setup is as follows:
Client(Caller)->dialup modem->PBX->FreeSWITCH->PBX-> 4 dialup modems->Server(Receiver)

I basically need FreeSWITCH to bridge the incoming call to the best external destination (out of the 4 available), so that the modem training, connection etc can take place smoothly, before exchange of data. I am not sure if mod_fifo would help me in this scenario, as, I would require an agent to dial in and read the fifo. Could you please clarify?

Thanks!

With regards,
Sirish

Sounds like you want to take a look into mod_fifo.
