Hi all, I have an issue that seems to have arisen (perhaps recently), that i'm unsure of how to resolve. We have a few customers in the Toronto, ON area where the outgoing CLID set as a Toronto TN (sourced from bandwidth.com i believe). when these customers dial canadian Toll Free numbers, the TFN provider rejects the call. we send these calls our our level3 EVT trunk. Level 3 states that they only support canadian TN's calling Canadian TFN's as "best effort".

we have the same issue sending the calls out Bandwidth, where they might likely send the call out Level3 as well. we have the same issue sending the calls out windstream.

has anyone seen this issue as well? i'm going to try a few more carriers.

thanks,

Hi Shri, Yes we see this a lot. The frustrating part is when the carrier doesn't give a 503 but instead plays a recording. We usually have good luck by first sending the call to our Peerless Networks trunks and then if they can't terminate it, they do 503 it and then we try 360 Networks (Onvoy Voip360). This has given us the best results. Carriers that we've tested that tend to play a message are O1 Communications and Hypercube, I've been told in Canada many carriers have to pay to terminate the Toll Free traffic reliably. I would suggest talking to Primus Canada to see if they can help you out. ~Jared

We have a mostly Canadian contact center clients and our clients frequently transfer to Canadian, as well as US TFNs. What we find is that when routing through Canadian CLECs, calls to Canadian TFNs tend to terminate consistently, with the exception when our clients don?t set a valid CLI. Some IVRs are programmed to ignore UNKNOWN/Witheld CLI (or US NPAs). But this is usually an IVR limitation, not the telephone network. Terminating to Canadian TFNs via US Carriers is spotty at best. Resulting in similar outcomes folks already mentioned? That being said. We are our own RespOrg, so I know for a fact it is possible to block US calls to Canadian TFNs and vice versa, based on LATA configuration. In fact for our clients, we use two different carriers to route Canadian calls and US calls to the same TFN, based on originating LATA. So sometimes the number itself will be limited to receive calls originating in Canada. It?s a mess J.
