Multiway

I am unsuccessful in connecting a Multiway call.


 


I have the following equipment


 


4501 MCU with software 4.1


VCSE with software 7.2.1. The VCSE has an external IP address


TMSPE with software 14.2.2


 


I also have a


C40 with softwareTC4.1 ( I know it’s out of date)


3 E20’s with software TE4.1.1


EX60 with software TC5.1.1


 


All systems are registered to the VCSE and TMS


 


I can make multipoint calls to the MCU from any of the systems.


 


The endpoints all have Multiway enabled. The Multiway address in all endpoints is WNESU-Multiway. This alias does register to VCSE as a SIP alias:

The VCSE has Conference Factory enabled with WNESU-Multiway as the Conference Factory Alias and 99977%%@ip address of VCSE as the Conference Factory Template


 


 


I have an H.323 search rule of:


 


Priority: 48


Protocal: Any


Source: Any


Request must be authenticated: No


Mode: Alias pattern match


Pattern type: Regex


Pattern String: (99977\d+)@ip address of VCSE


Pattern behavior: Replace


Replace string: \1


 


I have a Neighbor zone created of:


H.323: Off


SIP: ON


Port: 5060


Transport: TCP


Accept proxied registrations: Allow


 


This entry has a search rule of:

I can make calls from any of the endpoints to WNESU-Multiway and get to the MCU.


I can make calls from any endpoint to 99977@ip address of VCSE  and get to the MCU


I can make calls from any endpoint to 77@ip address of VCSE and get to the MCU.


 


From my EX60 I dial the C40, then put the C40 on hold and dial one of the E20’s. I then press the Merge key on the EX60.


 


The EX60 displays a message reading


 


Merging calls


C40


E20


My EX60 connects with the MCU and I hear a message saying I am the first to join the conference. About 5 seconds later I see a message that reads Merging Calls Failed


 


 


 Thanks for any suggestions

Multiway

The pasted html stuff is quite hard to read.

I recommend that you check out the deployment guide:

http://www.cisco.com/en/US/docs/telepresence/infrastructure/vcs/config_guide/Cisco_VCS_Multiway_Deployment_Guide_X7.pdf

some quotes from it:

Note that:

  •   The Conference Factory Alias must be a SIP URI that is routable to this Cisco VCS by every endpoint that wants to initiate a Multiway conference.

  •   The Conference Factory Alias will be registered to the Cisco VCS.

  •   The Conference Factory Template must result in a SIP URI that is routable by every endpoint that may be asked to join a conference – whether it is a SIP device or an H.323 device.
    In an integrated environment where IP PBXs may be requested to join a conference, these IP PBXs must be able to route calls to this URI.

  •   If the Template is creating a URI that will be routed to an H.323 MCU, typically the name part of the URI (name@domain) must produce a numeric only ID, as H.323 MCUs typically only support E.164 dialing.

  •   If calls are to be made to an MCU that supports SIP, it will register %%@MCU.domain ... make sure that is unique for SIP calls, so that it does not match other dialable SIP destinations.

  •   Make sure that the Template cannot generate URIs which match existing endpoint URIs or other Multiway conference URIs – otherwise calls may end up ringing endpoints or joining another conference.

  •   The Template is not replicated across cluster nodes and must be configured independently and uniquely for each node. See the separate section on configuring Multiway in a clustered environment.

    To ensure that the Conference Factory Alias is processed quickly, you are recommended to add a dedicated, high-priority search rule for this alias. The effect of this will be particularly beneficial in scenarios with many search rules and zones.

And actually I do not get the thought behind your deployment anyhow and some info are missing

(like which target zone you try to use with your search rules, why you add a h323 only search rule for it,

how you configured multiway on the endpoints, ...)

Also the log from endpoints and the vcs (also search and call history & details for the attempts)

What I would do:

* read the multiway deployment guide

* read the multiway deployment guide again

* properly implement URI dialing and domains, especially if you want to use sip

* see that you get encryption working and thats currently only possible with h323 towards the mcu (if you need encryped content) anyhow, h323 to the mcu still feels like a good idea on vcs deployments also for the

* properly set up the multiway uri on the endpoints (try to prefix it with the protocol you use, like h323: or sip: and also manually set the protocol, I would use the call protocol which you use as the default)

* read the multiway deployment guide again :-)
