Network Address Translation Situation

If you are behind a Firewall/NAT router, you have two options:

1. Portforwarding
2. STUN

Portforwarding

The following ports must be portforwarded from your Firewall/NAT router to your SPA:

• UDP 5060
• The UDP port range specified from SIP > RTP Parameters > RTP Port Min until SIP > RTP Parameters > RTP Port Max

STUN Support

SIP > NAT Support Parameters
 Handle VIA received: yes
 Handle VIA rport: yes
 Insert VIA received: yes
 Insert VIA rport: yes
 Substitute VIA Addr: yes
 Send Resp To Src Port: yes
 STUN Enable: yes
 STUN Test Enable: yes
 STUN Server: any public STUN server
 NAT Keep Alive Intvl: 15 (can be increased after you are confident everything is configured properly)

Line 1 > NAT Settings
 NAT Mapping Enable: yes
 NAT Keep Alive Enable: yes
 NAT Keep Alive Msg: $PING
 NAT Keep Alive Dest: $PROXY

Dial Plan

Add the following to your dialplan to enable 8-digit and 852-prefixed 8-digit Hong Kong phone numbers. This diaplan should be added before the final right-parenthesis ')' character.

Line 1 > Dial Plan
 Dial Plan: <852:>[23678]xxxxxxxS0|[236789]xxxxxxxS0

Therefore, if your original dialplan looked like this:
 Dial Plan: ([2-9]xxxxxx|011xx.|1[2-9]xx[2-9]xxxxxx)

The new HK enabled dialplan would be:
 Dial Plan: ([2-9]xxxxxx|011xx.|1[2-9]xx[2-9]xxxxxx|<852:>[236789]xxxxxxxS0|[236789]xxxxxxxS0)

Additionally, if you are still having problems, you might want to enable debugging on the SPA and submit the logs to the Linksys (Sipura) VoIP Support Forum or the VOIP Forum of BroadBandReports.com.
