asterisk users - Oct 2015 - AMI event PeerStatus: Address option with res_pjsip

Hello.

Continue to move from chan_sip to res_pjsip.
For the work of my algorithms is very important to know the IP address 
of all trunks and endpoints (phones).

In the case of chan_sip, I used PeerStatus AMI event through which was 
received the fact of online/offline and IP Address of endpoint. And 
requesting AMI SIPshowpeer I received UserAgent of this endpoint.

res_pjsip.
In the case of "ENDPOINT CONFIGURED FOR USE WITH A SIP PHONE" I can
use
AMI event "SuccessfulAuth" to retrieve IP Address.
How can I get the IP address in the case of trunks?
I will be grateful if tell me how to get the User agent.

Thanks

Dmitriy Serov.
