请教 dial plan 问题

ATA (SPA1001) + SS + G5 + GV已设好,一切正常,只不过每次用ATA电话,要拨1+ area code (302), 为了免拨1+area code (302),我在原先的dial plan (*xx|[3469]11|0|00|[2-9]xxxxxx|1xxx[2-9]xxxxxxS0|xxxxxxxxxxxx.)后加上<:1302>[2-9]xxxxxxS0成为(*xx|[3469]11|0|00|[2-9]xxxxxx|1xxx[2-9]xxxxxxS0|xxxxxxxxxxxx.|<:1302>[2-9]xxxxxxS0).可是当我拨local电话(without area code)时,听见的是忙音.谢谢.
