Hi,

I am new to FreeSWITCH and need an advice.

All calls to PSTN from our server will go through single gateway,
which is a soft switch supporting SIP protocol. FreeSWITCH will need
to register with soft switch, but soft switch permits only single
active call (in either direction) per registration. So we will need 10
SIP accounts to allow 10 simultaneous connections.

Are you going to have incoming calls as well? If so, how does the soft-switch handle two concurrent calls to the same number?

Question is - how should I configure FreeSWITCH for this scenario? I
see two options:

1) Create 10 gateways with different registrations, use mod_limit to
route only one outgoing call per gateway;
2) Create 10 gateways with different registrations, use event socket
to route calls manually and monitor used lines (incoming and outgoing
calls through soft switch).

Are there any other possibilities? Corrections/ suggestions are very welcome.

This seems like a serious defect in the soft-switch. I can understand if it allows you to specify only one call per SIP registration, but to hard-code that limit seems pretty silly. Can you find out more about the soft-switch in question and see if that limitation is flexible?
