Are those phones on an FXS or through an FXO to a PSTN to an outside number?

If these are FXS channels, then they should be of the form: Zap/<chan>. The
additional argument you have, the 206 and 221, should not be present, AFAIK.

	chanspec[c][d][rcadence][/phonenumber]
	...
	phonenumber, if present, specifies which telephone number you wish to be
	connected with. Note that this makes sense only when you are dialing a
	telephone line (an FXO or PRI interface), not an internal extension. Within

	the phone number, you may use the special modifier w to indicate a
	half-second pause. You might want to use this to wait for a dialtone or for
	a pause while dialing digits. You may also use the special modifier c to
	allow for clear channel connections between PRI ports.
