[Serusers] PSTN gateway user lookup

Hello,

I'm using ser with an AS5350 as PSTN gateway. On the AS i've defined:

sip-ua sip-server ipv4:1.2.3.4

and for every PSTN number I want to map to a SIP contact for inbound calls.

dial-peer voice 292 voip description test destination-pattern 0123456789 progress_ind setup enable 3 session protocol sipv2 session target ipv4:1.2.3.4 req-qos controlled-load ip qos dscp cs5 media !

Now calls for 0123456789 are forwarded to ser (1.2.3.4), but I need a way to make ser know who is going to receive the call.

I solved this adding a record to the alias table containing the PSTN address for incoming calls of each user, which is then matched in ser through lookup(aliases).

Does anyone use a different approach to solve this?

thanks a lot
