Connectivity and Bandwidth Requirements
One-way latency (mouth to ear) no more than 150 ms
100 kbits UP/DOWN per concurrent voice call, plus web traffic bandwidth for the Daktela web interface (average is 100kbits DOWN for each active working agent)
Loss no more than 1 percent IP exchanges, VoIP networks
Average one-way jitter targeted at less than 30 ms
Optional: Voice traffic should be marked to DSCP EF per the QoS Baseline and RFC 3246
When using a firewall, the customer must configure and change it for the VoIP and data stream to allow communication between the on premise instance, its phones and the Daktela platform
Disabled SIP-ALG on LAN devices and firewall, as default. May be enabled in some specific cases.
Due to their complexity, Daktela doesn’t provide support for customer LAN infrastructure and firewalls!
Professional LAN network infrastructure based on min. full duplex 100 Mbit/s switches and of type CAT5e or better.
The network must not run at full capacity even during peak hours. Adequate capacity must be available for the anticipated voice traffic. It is ideal to separate and prioritise the telephony data, e.g. via VLAN.
Separate switches for IP phones and PCs are recommended for high volume data exchange over the local network.
IP phones must be assigned a valid IP configuration including internet gateway designated for voice traffic by means of a DHCP server.
