Incoming call does not work - asterisk

Question

Enviroment
2 VMs
One with Debian 8, Asterisk 13.13.1, PJSIP 2.5.5
and the other wit Debian 8 Gnome-GUI and SFLphone 1.4.1
VMs are located behinde NAT router in same network
Way around NAT is done by Exposed-Host function on the Asterisk-VM static IP
Asterisk-VM Firewall is turned of, to do so I have done in CLI as root:
iptables -F
iptables -X
iptables -t nat -F
iptables -t nat -X
iptables -t mangle -F
iptables -t mangle -X
iptables -P INPUT ACCEPT
iptables -P OUTPUT ACCEPT
iptables -P FORWARD ACCEPT

Problem
Incoming calls are not routed to my softphone 1001. Only thing i get is 10sec silence, then HangUp. External calls run perfect
Thanks for help or link or calling me a dumbf*uck and telling me it's obvious
I use this enviroment just to learn, it's not productive neither 24/7 runnig. If you're missing something, tell me

Answer 1

Solution
This line in debug.log brought me to it
[Mar 20 06:46:59] DEBUG[25618] res_pjsip_endpoint_identifier_ip.c: No identify sections to match against
Two things to change in pjsip.conf
One very silly mistake by myself.
You have to change this lines
[sipgate_identity]
type=identity
To
[sipgate_identity]
type=identify
and second:
sipgate gave me some other errors, so it seems like it does not work with alaw,
so I changed it to gsm
See
[sipgate]
type = endpoint
...
disallow = all
allow = alaw
...
changed to
[sipgate]
type = endpoint
...
disallow = all
allow = gsm
...
