Description:On Friday I had 5 SIP calls dropped and the only messages I saw in the debug before they dropped is this:

Jan 23 15:18:26 DEBUG[78200848]: Difference is 175056, ms is 21902
Jan 23 15:18:26 DEBUG[77774866]: Difference is 88280, ms is 11055
Jan 23 15:18:26 DEBUG[77627418]: Difference is 171472, ms is 21454
Jan 23 15:18:26 DEBUG[78233624]: Difference is 174120, ms is 21785
Jan 23 15:18:26 DEBUG[77807635]: Difference is 172360, ms is 21565

none of the other active SIP calls dropped on the server. All of these calls were Zap -> SIP.
All phones are through Sipura adapters with the same firmware.
All Adapters are going through an HP Procurve switch

I've never had a problem with this before. Is this just a network latency problem? if so how can it be prevented?

Reset your sipura's and asterisk and try to duplicate.  Its something to do with rtp I suspect but could be network related in some way.
