Re: Call Forwarding from One Site to Another

aniket0422 · ‎04-11-2022

We have 2 sites, Lets assume site A and Site B. Both sites have their Local PSTN gateways. Geo Location Polices are in Place for both location and Local Route Group is configured.

Site B user have enabled "call forward no answer" to Mobile Number on his IP Phones.

So, When site A user calls site B user - Phone rings for 5 seconds and then call gets dropped, This is because Site A user can not use Site B PSTN gateway to connect to the "Call Forward" destination as per Geo Location Configuration.

Is there a way, Site A can use Local gateway at Site A to reach to the "Call Forward" destination of Site B User.

If you are using Standard Local Route Group feature, the service parameter Local route group for redirected calls" defines, which local gateway should be used for such scenarios.

If you are not using it, then the behaviour that you described is like that, because you configured it like that.

Hi,

As @b.winter mentioned kindly check and use "Local route group of calling party" for Local route group for redirected calls in the call manager service parameter.

- This parameter specifies the local route group to be used for a redirected call.

Local route group of calling party: When this value is selected, the local route group associated with the Device Pool of the Calling Party is used for routing the call.
Local route group of original called party: When this value is selected, the local route group associated with the Device Pool of the Original Called Party is used for routing the call.
Local route group of last redirecting party: When this value is selected, the local route group associated with the Device Pool of the Last Redirecting Party is used for routing the call

Ensure that you have configured SLGR for PSTN routing

Ensure that you have selected Route group which contains the local gateway to the device pool Standard Local Route Group section.

You may find the blog here more on SLGR configuration

This is because Site A user can not use Site B PSTN gateway to connect to the "Call Forward" destination as per Geo Location Configuration.

Have you taken debugs from the site B gateway ? does the call lands on the Site B gateway?

For forwarding calls Check if ISP is rejecting the call due to the ANI. Most ISP will drop calls or translate to the Pilot number if calling information is other than the DID block.
