Mitel 5000 inserting pause in call forward path

[Crowtalks]

I have a Mitel 5000 HX 4.0 using a PRI where the customer has recently added account codes that are being controlled by the telco.

Extension 4249 wants to forward his extension to his LD cell phone which happens to generate the call accounting tone. What does Mitel use as pause to enter in the dial string before I enter the account code?

Example CF to: 1-615-555-1212 (pause) 123456

Thanks, Jim
