Hi,
I'm very new to this list.
In my setup I use openser as proxy an asterisk as pstn gateway.
I want to implement a 'follow-me' service, i.e. I want users to dial a
particular number and then
they can enter a phone number where receive their incoming calls.
So which is the best solution: use asterisk to perform a lookup in the
DB and decide to which number route the call,
ore use openser maybe with the 'exec_dset' command?
Or there is a command that I'm missing that can implement this function?
Thanks in advance,
Cosimo
You probably want to use Asterisk or some other back-to-back user agent
for this, because many PSTN gateways will not take kindly to having call
legs looped back into them with the same corresponding IDs and tags that
characterise the outgoing SIP leg to OpenSER built to broker the
transaction.
Unless you use different PSTN gateways for inbound and outbound, of
course. In that case, you can use OpenSER and just do a database lookup
and rewrite the SIP destination URI with the new number.
