Trunk Between 7.0 and 4.0

Hi,

Is it possible to make a trunk connection between two call manager and make a line between them. So if we can make a trunk does these phones make rtp between each other with their own ip address' or via call manager ip address?

thanks

Re: Trunk Between 7.0 and 4.0

will be between the Phones,

but i suggest to use : Intercluster Trunk (Non-Gatekeeper Controlled)

--------------------------------------

Intercluster Trunk (Non-Gatekeeper Controlled)

In a distributed network that has no gatekeeper control, you must configure a separate intercluster trunk for each device pool in a remote cluster that the local Cisco CallManager can call over the IP WAN. The intercluster trunks statically specify the IP addresses or host names of the remote devices.To choose this method, use Device > Trunk and choose Inter-Cluster Trunk (Non-Gatekeeper Controlled) in Cisco CallManager Administration.

--------------------------------------------------------------------------------

Note You must specify the IP addresses of all remote Cisco CallManager nodes that belong to the device pool of the remote non-gatekeeper-controlled intercluster trunk.

--------------------------------------------------------------------------------

You also configure the necessary route patterns and route groups to route calls to and from the intercluster trunks.

SIP Trunk

In a call-processing environment that uses Session Initiation Protocol (SIP), use SIP trunks to configure a signaling interface with Cisco CallManager for SIP calls. SIP trunks (or signaling interfaces) connect Cisco CallManager clusters with a SIP proxy server. A SIP signaling interface uses port-based routing, and Cisco CallManager accepts calls from any gateway as long as the SIP messages arrive on the port that is configured as a SIP signaling interface. The SIP signaling interface uses requests and responses to establish, maintain, and terminate calls (or sessions) between two or more endpoints.

To choose this method, use Device > Trunk and choose SIP Trunk in Cisco CallManager Administration.

You must also configure route groups and route patterns that use the SIP trunks to route the SIP calls.

For more information about SIP and configuring SIP trunks, see the "SIP and Cisco CallManager" section.
