[cisco-voip] How do I share a line in two locations?

Sorry - forgot to include that you have to create a AcmeDevice_MAC_PT to hold the route patterns and then put that in the AcmeDevice_MAC_CSS.

  It may take a bit of a redesign of your dialplan, but here's what I would do:

  Create AcmeDevice_MAC_CSS and in that create your route patterns to access the PSTN (including 911 and 9.911) and send them out the MAC gateways.  This would include all PSTN route patterns.

  Create AcmeDevice_SAL_CSS and in that create your route patterns to access the PSTN (including 911 and 9.911) and send them out the SAL gateways. This would include all PSTN route patterns.

  Create a few partitions which have route patterns which block certain PSTN patterns:
    a.. Acme_PSTN_OnNetOnly_PT : this would block all PSTN access except 911 and 9.911 
    b.. Acme_PSTN_LocalCalls_PT: this would block everything except local calling, perhaps directory assistance too. 
    c.. Acme_PSTN_LongDist_PT: this would block international calling 
    d.. Acme_PSTN_Unlimited_PT: this would block only restricted calling such as 1-900 numbers 
    e.. Acme_PSTN_Unrestricted_PT: in actuality, you don't need this partition! if you want to assign unrestricted access, just don't include the PSTN access partitions.
  Give the MAC phone the AcmeMAC_CSS, give the SAL phone the AcmeSAL_CSS and give the shared line the CSS that it needs to access your onnet resources....just make sure to put the appropriate PSTN partition in that CSS so that you are blocking the shared line from accessing what it shouldnt. This way, when the calls to the PSTN are made, they go out the appropriate gateway.

  Now, that all being said, you can make the PSTN partitions and complicated or as simple as you'd like. Working here, I know that as soon as I put any restrictions on something I'll be asked to make an exception for somebody high up.... ;) So I built our dial plan accordingly to do that. Here's a look at what my device calling search space looks like and what some of my PSTN blocking partitions look like (see attachment). 

  I'm more than welcome to discuss this live - email doesn't do it justice. ;)

    That is what I'm looking to do.

    But I don't think I have a good grasp of what you're saying I need to do.  Can you expand.

    Remote location (PRI VGW) extension 5925

    Central site (VGW 3 PRIs) extension 5925

    Extension 5925 comes in on the remote location.  Lets call the partition "MAC"  we will call the central site "SAL".

    Central site 5925 is in the SAL DP and remote site is in the MAC DP.  Same with location, etc. (main phone config page)

    Call comes in at the remote site and rings both phones with extension 5925 and both the central and remote site.

    Problem.

    Because it's a shared line appearance both phones are using the MAC partition, MAC CSS (line config page).

    Question

    How do I get the SAL phone to use the Central Site's PRIs for the 9.@ and the remote site's PRI's for the remote MAC Phone?

    Thanks

    Scott

    Hi Scott. Our two cents are worth about 1.62 of yours - but we do have Tim Horton's coffee. ;)

    Anyways, I haven't used locations for the use of codecs etc and I'm not sure if you can have the same DN/partition on different phones in different locations, however, one of my colleages did something similar and had it working.

    What I gather from what you are looking for is the ability for people to dial out the appropriate PRI when at the different physical locations. If that's what you are looking for, then I think the line/device approach is what you need. We did this for that reason and also to prepare for extension mobility. We gave the phone access to all PSTN route patterns and then restricted the line by putting a partition in the line's css that blocked particular route patterns. This way here, you could put the shared line at each location in the same partition and they would work in unison, both ringing at the same time. When the person dials 9.@ it will go out the appropriate gateway.

    Is this what you were looking for or did I read your message incorrectly?

      I have two sites that are in different calling areas but have users that are
      based out of both sites.  Remote site has a Single PRI and the central site
      has 3 PRIs.  They want there extension at each location (shared line
      appearance).  Do I put both extensions in the location (partition) that the
      extension is supposed to be at?  Then all calls from the central site will
      go out the WAN to the remote site to dial out?  How is the best way to work
      this?  I already have toll bypass working so it really only comes down to
      long distance calls.  What is everyone's two cents worth?
