question on TN and call back number

Just received my TN the call back number is a 1-800 with extension number is this ok?

My previous TN had a personal number but this 1-800 number is the first i have seen. Is this something the Visa officer can ask me to go back and correct?
Just want to know in advance.

Thanks

By "received my TN" I assume you mean the TN letter from your employer?
The number is not an issue.

Duh!!! Sorry, you are correct received the letter.
Last letter they send had a Canadian phone number so i asked them to correct it. Funny they just send a bunch of Canadians last month on the Canadian telephone number and it seems like none of those guys had any issues.

Maybe they don't care i am sure with me it will be the opposite
