Yes.<\/p>\n\n\n\n
However, you should know that not all IP telephony companies will allow CentrixOne to connect to their \u201cAPI.\u201d So, we advise you to check the list of compatible companies with your CentrixOne account manager.<\/p>\n\n\n\n
Most IP phone companies use the character \u201cx\u201d to denote an extension number. So, you could write your phone like this: 514-222-3333 \u00d7 444 (444 is the person\u2019s extension). Depending on your contact\u2019s phone system, the extension may even dial automatically. How convenient!<\/p>\n\n\n\n
Normally, mobile phones use the same logic.<\/p>\n\n\n\n
We still recommend that you check with your IP telephony provider for the character or format to use to indicate an extension number.<\/p>\n\n\n\n
