Your problem here probably lies in you are most likely using an analog
line for the zap portion. Since analog doesn't know when the other side
answered or not, it assumes answered and stops ringing your SIP phones.

IAX2 would help, but only if you where using a provider who had a PRI or
T1 line that knows when the other side answers the phone.
