SIP Registration and Cisco ASA

My company is using a hosted SIP service for its phone system.  Everything but Linksys SPA-2102's (Dig to Analog Converter) is working fine.

The Linksys Device's will properly register with the SIP server and will work for 5 minutes.  Then they will not work until they register again; and then again only for 5 minutes.  The ATA's are configured to register every hour, if I change this to 5 mins; things work fine; but I'd like to get this fixed in the firewall.

The Polycom 450's do not have this issue, why the difference?

In the ASA I've created a punch through, but this has not corrected the issue.

object-group service SIP_PORTS
 service-object tcp eq sip
 service-object udp eq sip
 service-object tcp range 10000 20000
 service-object udp range 10000 20000
object-group network SIP_SERVERS
 network-object x.x.x.96 255.255.255.224
access-list outside_access_in extended permit object-group SIP_PORTS object-group SIP_SERVERS any
