Put the following in the dial field of the custom extension:   SIP/trunk/number|timeout|rD(digits)   For example:   SIP/telasip-gw/1234567890|30|rD(ww2w110)   “r” is for generating the ring for the calling party and “D(digits)” are the digit to play (DTMF) to the called party before bridging the calls. It can be used to dial an extension. It’s nice because we can add dial options directly in freepbx without having to hack config files. Another example of this is you could create a custom extension 211 and in the “dial” text box you could enter: Local/[email protected] If you dial ext 211 then the system will dial 18005551212 as an out bound number. This can be quite handy if you want to dial a mobile number
