How to configure TEHO


TEHO can be configured by using Route Groups and Route Lists in CUCM. I will give you a small example and I hope it will make things clear:

You have to sites, one in SJ (1408XXXXXXX) and one in RTP (1919XXXXXXX).

Now if someone from SJ wants to dial a number that belongs to RTP then you have to create two route group one contains SJ voice gateway and the other contains RTP gateway.

Then you will create one route list and add the RTP route group as a first choice and the SJ as second choice. Now from route list details you need to modify each route group as following:

1 -For RTP route group: in Called Party Transformations do discard digits (NANP:PreDot) and prefix with 9.

2- For SJ route group: you dont need to do anything.

Now create a route pattern 91919.XXXXXXX and point this to route list you created. In this scenario if RTP site is available then the call should go through this site, otherwise it will choose the SJ site for routing this call.

Also it will be easy to achieve this with Local Route Groups at it will simplifies call routing in CUCM, please take a look on the following link:

How to configure TEHO

Also, check out CUCM SRND for some examples around TEHO configuration. My view of TEHO is that unless you are in countries where long distance is still expensive this is not worth it as bandwidth is more expensive than minimal LD charges. Again, may vary by country/customer.

Also some country do not allow TEHO. You will have to check locally if your country law supports carring PSTN voice traffic on WAN.
