Inbound Call Issue

Answered Question

Hello All

Just wondered if anyone has any ideas about the following.

We have a site which has 2 ISDN2e Circuits & have installed a 2 BRI Expansion into the UC520.

We had a issue on Friday with inbound calls not working so a TAC was raised and a Cisco engineer dialed in and set a translate from the main number to a 1000 extension which makes all the attached phones ring.

Today I've found that we're only able to have 1 inbound call at a time,  Does anyone have any thoughts?

Many Thanks

Stuart.

I have this problem too.

1) Telnet or SSH to your UC500. Log in.

2) Issue the "enable" command and type in your enable password.

3) Do a "show running-config" and look for the "ephone-dn" with "number 1000" in it. If it doesn't have the keyword "dual-line" next to it, then this is a single line DN.

Since you have a couple of BRI's, an octo DN will be just perfect. Do the following:

1) Once you have identified your ephone-dn, copy its configuration (subcommands) to a text file.

2) Delete the DN by going into configuration mode ("config terminal") and doing a "no ephone-dn XX", where XX is the DN index.

3) Enter the command "ephone-dn XX octo-line" to create this DN as an octal directory number.

4) Paste all the subcommands that you kept in the text file.

5) Exit config mode and save your changes ("end" and "wr mem")

The end result is a DN that looked just like your other one, but wit the "octo-line" option next to it.

Please test this and let us know.

It sounds to me like extension 1000 is set up as a single line DN - ie it can only support one call.  Was this system set up using CCA or manually using the command line?  CCA will create directory numbers as dual channel which would allow you to have two calls happening simultaneously, but if you are using the command line and do not explicitly use the dual-line or octo-line keywords, then you will get a single channel line created.

In any case, a more typical way to handle this is to translate the incoming range to a hunt group pilot number that rings multiple phones.  That way you can support as many calls as you have people to answer them.  Alternatively you could direct the inbound calls to an Auto Attendant that plays a message and allows the caller to select where they want to go from a menu of options.

Cheers,

Dave.
