Least cost routing

[Eswari mani]

Is there any workaround or solution available to this problem? Is it possible to use least cost routing for Site A and Site B number so it will local call for us from Site C .

Site A number range is +63,Site B Number range is +61 and Site C is +91 but Site C needs to use Site A number range and the calls should be considered to local calls.So please let us know the possible ways.

Hi Eswari mani,

 if my understanding is correct ... what you want is: a call from Site C to +63 range should go to Site A, via VoIP, and leave the PSTN as a local call ... the same to +61, but via Site B.

 If the above is correct ... read the following doc: TEHO doc.

Hope this helps.

Hi Eswari,

As suggested by Marcelo, the concept is called TEHO. The best practice is to globalize your DIDs through called/calling transformation patterns at the gateway level.

The next step will be using a combination of route-patterns, CSS, PTs to route the calls based on the called number out of the right gateway.

The main challenges I saw with TEHO were :

1. CDRs to be able to trace calls and get call logs correctly

2. Local capacity of each gateway/trunk to make sure that you aren't overloading some sites and causing calls to be dropped
