Most import pre-requisite is to run latest IP Office firmware release. I am running R9 on my IP Office 500v2. On the web I tried to find some help how this SIP trunk could be established; unfortunately I didn’t find any post that guided me through the whole process. I am publishing my setup and I hope others will have find their way easier than I did.<\/p>\n
My objective<\/strong><\/p>\n My environment<\/strong><\/p>\n Before you start make sure that mediation server has been configured to listen on TCP port 5060. I also needed to adjust the Windows Firewall<\/strong> as this TCP 5060 port is not enabled by default.<\/p>\n IP Office firmware SIP Licenses System configuration<\/strong> \u00a0 System \/ LAN1 \/ VoIP SIP line ITSP Domain: Networknet.nl Transport<\/strong><\/p>\n ITSP Proxy Address: 192.168.200.9 (IP address of the Lync Mediation server) SIP URI Local URI: * Create channel 2<\/strong><\/p>\n Local URI: Use Internal Data VoIP<\/strong><\/p>\n Custom codec is selected for G.711 ALAW 64K. That’s it. The SIP line configuration has now been completed.<\/p>\n Any URI with Networknet.nl will go through Dial feature and line group 21 this is outgoing group channel for the SIP trunk to Lync server.<\/p>\n Code: N; New short code is needed to reach any Enterprise Voice enabled users or to a Dial-In Access Number. I am sending this traffic over the ASR group that I created with 54 ID.<\/p>\n Code: *5962XXX (*LYNCEXTENSION) Configuration for IP office is basically done. One tweak I implemented in addition is to add additional ASR codes for my main route:<\/p>\n Any Lync calling number that was entering IP Office added two additional zeros (00). This way I didn’t need to implement any further configuration on IP Office and kept the configuration lean by removing them at my Main ASR route.<\/p>\n Make sure TCP and port 5060 range is set for Lync Meditation server.<\/p>\n Now I will create new PSTN gateway from Lync Topology builder to my IP office<\/p>\n FQDN: ipo.networknet.local<\/p>\n Make sure that IP Office has been registered with an HOST A record for DNS<\/p>\n Enable IPv4<\/p>\n Trunk name: ipo.networknet.local SIP trunk is created and I updated my Lync Topology that is ready for publishing.<\/p>\n One of great things I learned some months ago when going to a Microsoft Lync Enterprise Voice training is the following website. https:\/\/www.lyncoptimizer.com\/<\/a> has optimized set of dialing rules for 80 countries that will work with Microsoft Lync Server 2010\/2013. It helped me to start with a working Voice Routing configuration. At first I couldn’t figure out where to start and after the rules were created I got better understanding how voice policies work.<\/p>\n I run the script on my Lync server by selecting my Networknet site and creating user-level dial plan.<\/p>\n After the script finished I refreshed Lync Control Panel. It created new Dial Plan and defined required normalization rules for calling out to +31 PSTN network<\/p>\n Pretty cool! Saves a lot of work and worked for me immediately without need to troubleshoot from Lync server side.<\/p>\n The script associated my IP Office trunk with a route. In screenshot below you can see the +316 pattern for mobile network<\/p>\n After running the voice routing test I could confirm everything was setup.<\/p>\n I used my Lync client and I could dial out through my new configured SIP trunk. My mobile phone was ringing.<\/p>\n This is an example mobile number :). Sure it worked with my own.<\/p>\n\n

<\/strong>Make sure to have SIP Trunk Channel license. I have 10 channels in total.<\/p>\n<\/a><\/p>\n
Make sure SIP Trunks Enable is checked.<\/p>\n<\/a><\/p>\n
SIP Trunks Enable: checked<\/p>\nCreate new SIP line<\/h3>\n
<\/a><\/p>\n
<\/strong>I am creating new SIP line with line number 18.<\/p>\n<\/a><\/p>\n
National Prefix: empty
International Prefix: empty
Check OOS: unchecked
All other options should be kept default when line is created.<\/p>\n<\/a><\/p>\n
Layer 4 Protocol: TCP
Send Port: 5060
Listen Port: 5060<\/p>\n
