Use Lync with external SIP accounts RRS feed

  • Question

  • I am sorry if this is a stupid question, but I couldn't find any information on that. We are a pretty small company that use VOIP for our communications. We pay monthly to a provider that provide us a domain to connect to, a username and a password. All our users have an SIP account that we configure to a standard VOIP client. (We are currently using X-Lite) I installed Lync internally so that we can all communicate with the chat system of Lync internally and create meetings easily, but I would also like our users to have their phone line with their Lync client. It would be nice if I was able to setup a SIP account to connect to our external provider, so that we could use Lync for phone calls to.

    We also have people that are using hardware phones that connect to that external provider, so I would like to be able to select whether or not the user receives his call through Lync. If I don't set an SIP for him in Lync, then it would be through his real phone.

    Thank you for taking the time to read this, and I would really appreciate if someone could tell me if this is doable, or how we could achieve this.

    Sincerely,
    Louis

  • You can only connect optimized Phones like Snom or Polycom to Lync. For a SIP Trunk you need a Provider tha support a SIP Trunk to Lync. You can also Use a Gateway from Audiocodes to connect external lines or a Session Boarder Contoler to use a normal SIP Trunk.

    If you install a lync EDGE Server it will be possible to communicate with MS Live Client, AOL or Yahoo and with other customers who have installed OCS/Lync.

  • Hi,Louis,

    I am not sure if I understand your post correctly,if you are talking about Lync integrated with X-lite and SIP trunk hope this article can help you figure out the issue.

  • Louis,

     

    To get phone connection for your Lync users you need to talk to your VOIP provider about SIP trunk. That trank can be terminated on Lync (Mediation Server) and you can assigned phone numbers to your users after that. If you use Exchange in your environment you can configure UM on it (it is a licensed feature) and use AutoAttendants and Subscriber's Access (voicemail). In this case you can use extensions instead of DIDs.

    Additional benefit is an opportunity to use Lync as a conferencing bridge.

    I am not sure though if you will be able to use both sip-phones and trunk at the same time, please consult with your VOIP provider.

    Generally via SIP trunking you can use all of sip device and account with Lync, does your VOIP server support SIP trunking ?

  • Hi Everyone,

     

    Thank you very much for your replies. Unforntunately, this is not the scenario I was trying to get working Sharon.

    Aliuc, yes my provider support trunking, but since they don't know Lync, they don't want to help at all, they told me they could get me a trunk, but won't explain me what to do with it.

    I am not sure if what we are trying to do is achievable with trunks either. The problem is that I still want my provider to receive the call and bridge the calls with the extensions. They take care of the answering machine, all the extensions, voice mails, etc... We currently have many users that have physical phones and I would like them to still use them the way they are doing right now. Can I use trunking so that all calls are coming from my provider, and they are the ones filtering the extensions? For example, extensions 206, 205 and 207 would use Lync to receive calls, but extensions 208 and 209 would be received by physical devices. Do you know if this is a doable scenario with trunk?

    Thank you very much guys, I REALLY appreciate the help.

  • yes it is doable with your provider help. in this case you will use trunk for your Lync users only; other extensions may connect to the provider proxy directly.

    But - your Lync users will not be able to use your provider for voicemail(and probably for autoattendant, depending how much your provider will wish to help you) - Lync normally uses Exchange for it.

    It is not great your VOIP provider cannot confirm their trunk work with Lync - not all providers can do it unfortunately at this point (Microsoft has a list of verified ITSP - http://technet.microsoft.com/en-us/lync/gg131938#tab=4 goto SipTrunking)

  • hi you can do this, you need tcp trunk to provider, if you have internal system may be asterisk or another, you can also integrate this to lync. you must destroy x-lite, its so beutiful when you have everything in lync. you can try cx 300 usb phone or cx600. its very good solution for small organisation and not only small, its for enterprise solution.
