Greetings, im currently in the process of configuring a QoS policy between two sites connected using ADSL2 links and IPSEC/GRE tunnels.
The phone system, an NEC SV8100 is located at the head office and serves local phones it is also connected to an ISDN PRI, the branch office houses 10 IP phones which are registered with the NEC system via the GRE/IPSEC tunnel, i have been informed that the phones use SIP for call setup and teardown on port 5060,5070 and 5080.
NEC IP Address: 192.168.10.100
NEC VOIP Media Address: 192.168.10.102
Intersite Codec: G729
DSL Connection: 8000Kbps/792Kbps
Im very much aware of how i would do this with a Cisco PBX as i deploy CME all the time but could i check that the following policy is suitable for intersite voice traffic please, i intend to replicate this at the head office also on an ADSL2 circuit.
