請教 dial plan 問題

ATA (SPA1001) + SS + G5 + GV已設好,一切正常,隻不過每次用ATA電話,要撥1+ area code (302), 為了免撥1+area code (302),我在原先的dial plan (*xx|[3469]11|0|00|[2-9]xxxxxx|1xxx[2-9]xxxxxxS0|xxxxxxxxxxxx.)後加上<:1302>[2-9]xxxxxxS0成為(*xx|[3469]11|0|00|[2-9]xxxxxx|1xxx[2-9]xxxxxxS0|xxxxxxxxxxxx.|<:1302>[2-9]xxxxxxS0).可是當我撥local電話(without area code)時,聽見的是忙音.謝謝.
