I'm using iax2 interconnection between two asterisk (1.2.9.1) boxes, also using jitterbuffer, because this is over cdma, codec ilbc jitterbuffer is working fine, except some gaps in speech....

I'm not using ztdummy (and no digium hw) on my iax asterisk boxes, can it be source of my issue with gaps in speech over iax? Is ztdummy really needed for simple iax-iax interconnection (i.e. not trunking config)?
