Hello all,

 

We have a remote site that uses IP335 phones running 4.0.1.13681.  They connect back to us over a MPLS circuit where our Interactive Intelligence phone switch is.  The issue we are having is the phones get an IP address in their correct VLAN from the local DHCP server at the remote site but they will not register with the phone system here.  I can ping the phones from the main site so basic routing seems to be working.  The firewalls, in order to troubleshoot, have been set up to allow all traffic between the two sites.  The weird thing is if we add a DHCP reservation using a completely different IP address then they register back with our phone system and work just fine.  Anyone seen something like this or need additional information?
