outbound calling for a simple phone number works well (+1555 666 7777) but about 30% of my contacts have extension numbers in the phone number eg: (+1555 666 7777 p 234. it work fine when dialling on GSM but I cant dial those number with skype as it says incompatible number. some times i dial my bank and the number looks like this (+1 555 666 7777 p1p3p34567) there are lodes of phone serveses i use where i enter in numbers after I call. I cant use those numbers in skype out.
