I see the tsilo module works only with registered contacts using location table. Is there a possibility that the ts_append function can actually take the destination URI as an argument and append branch to respective destination?

Basically I want to avoid maintaining location table. In a typical mobile use case, where the incoming call is suspended and a push notification is generated to the called party; the called party generates a REGISTER request with expires header as 0; kamailio just extracts the contact header and sends the call. 

Problem comes in when the same user receives a PUSH on another device; I cannot figure a neat way to append the same call on the new device.

Is there a better alternative to achieve this without looking up the location table. Thanks for any help.
