I am a senior consultant working for a company called DIPS ASA (we develop electronic health record systems among other things), where I work with the internal IT dept. My main field of expertise is Microsoft Lync, but I am also a Cisco CCNA and UC consultant (certification pending).
I live in Bodø, in the northern Norway. Although I have an exciting job and three kids to manage I still try to find some time to share my experiences from everyday life as I am very fond of my job / hobby.

I would be interested in some consulting. Please send information.
I found your article (https://stoknes.wordpress.com/2013/08/31/redirecting-inbound-pstn-calls-in-lync/) very interesting. I am most interested in the Fax use case. Do you have a walk-through that speaks to SIP traffic redirection to a Fax service?
Hi Rune,
I have some problem with Lync Edge.
Lync message between 2 networks only work one way
I am able to Instance Message(IM) and see the presence information of the internal users, however the internal users (internal network) cannot reply my IM (external network).
I don’t have public IP address, I want to connect Lync Edge Server with 2 different networks.
I have set up a VMware lab environment (internal network) with 3 servers:
– Domain Controller Server (with DHCP, DNS, Certification Authority), Full computer name: W2012R2QA2.pronexuslab.com (domain:pronexuslab.com), IP: 10.89.89.1 (internal network) and IP: 10.207.241.11 (external network), OS: Window2012R2
– Lync Front End Server, Full computer name: W2012R2-Lync.pronexuslab.com (domain:pronexuslab.com) with Lync Server 2013 Standard Edition, IP: 10.89.89.2 (internal network), OS: Window2012R2
– Lync Edge Server, Full computer name: W2012LYNCEDGE.pronexuslab.com (not a member of the domain), IP: 10.89.89.3 (internal network) and IP: 10.207.241.12 (external network), OS: Window2012R2
Lync Edge Server:
I have 2 networks one internal (the VMware lab environment with domain:pronexuslab.com) and one external(with physical computers, other domain), I have set up a Lync Edge Server with 1 IP address to connect to an external network and another IP address to connect to the internal network.
Internal server FQDN : W2012LYNCEDGE.pronexuslab.com
Internal IPv4 address : 10.89.89.3
Federation (port 5061): Enabled
XMPP federation (port 5269): Disabled
Internal Configuration Replication Port (HTTPS): 4443
External FQDNs with single IP address:
Access Edge Service : edge.pronexuslab.com, IPv4 address: 10.207.241.12, Port:5061, Protocol: TLS
Web Conferencig Edge Service: edge.pronexuslab.com, IPv4 address: 10.207.241.12, Port:444, Protocol: TLS
A/V Edge Service: edge.pronexuslab.com, IPv4 address: 10.207.241.12, NAT: Disabled, Port:443, Protocol: TCP
I have also set up a Web Application Proxy on Lync Edge Server.
Users:
I have created 4 users: u1@pronexuslab.com, u2@pronexuslab.com, u3@pronexuslab.com, u4@pronexuslab.com
I also have installed the Lync Client Basic 2013 on each server (u1@pronexuslab.com on Lync Edge Server, u2@pronexuslab.com on Domain Controller Server, u3@pronexuslab.com on Lync Front End Server)
Test 1: User1 can send instant message and chat to User2,User3 and vice versa without problem. (users on internal network + user on Edge Server can sent instant messages and chat without problems)
Test 2: I have my physical PC (external network) with u4@pronexuslab.com I can sent IM (Instant Message) to User1, User2 and User3 (they can receive the message), but they can’t sent an IM to User4

Question:
Do I need to open ports on the Edge Server firewall and Client’s firewall for internal network and external network?
Thank you for your help.
Oscar Osorio
Hi Oscar.
From what I can see it looks like you have a DNS issue, where the Front End cannot resolve the IP address of your Edge server FQDN. Verify this by pinging or resolving (nslookup) the FQDN from your Front End.
Firewall exceptions Are generated automatically when running Deployment on server or client installer.
Best regards,
Rune

Hi Rune,
Thanks for sharing your smartdock experience.
I have the same query : “how can we use PXE install instead of USB key ?”
You write “The latter can be a pain, because PXE booting a Surface Pro 4 turned out such big a problem I had to go on using USB bootable media instead”…
What kind of configurations did you test ?
Do you know if a network solution would be possible ?
Best Regards,
Jean-Noel
Hi Jean-Noel.
I haven’t done any testing on the subject afterwards, as we have only deployed a few number of systems. It is probably possible to PXE boot using native USB-Ethernet adapters made for the Surface Pro 4 like others have suggested in their comments, but I have not heard of it being confirmed.

Hi Rune,
Nice blog and intro.
In SFB, how to enable call forwarding for the external incoming calls only to the SIP?
Thanks,
Amer
Thanks for the feedback.
Do you mean like internal calls not getting forwarded, only external calls? In that case there is no native support for that in Skype, but there are some third-party tools (like Competella Routing Agent) which will let you set forwarding options based on internal or external originating party.
Hope that helps!
