LQ-SIP Bandwidth Consumption
I would like to know the bandwidth consumption for the LQ, when I’m using 8 LQ lines which are connected simultaneously. please could you provide an estimation ?
Here is the answer to your question for the LQ consumption:
Each SIP call takes 64kbps for audio (G.711 or G.722) + RTP overhead for 20 ms packets (42bytes/packet * 50 packets per second = 2kBps or 16kbps) so 80kbps.
Each LQ sends a keep-alive to the SIP server every 15 seconds, not significant in bandwidth. 8 SIP calls would be 640kbps, 50 would be ~4Mbps. That is standard for any SIP call of this nature, LQ or not.
