Does g711ulaw uses only 160 bytes?

Hi,

When I run "#show sip-ua calls" command, it shows 

"Negotiated Codec : g711ulaw (160 bytes)",   

as mentioned here http://www.cisco.com/en/US/docs/ios/12_3t/voice/command/reference/vrht_s08_ps5207_TSD_Products_Command_Reference_Chapter.html#wp1370370

 

But when I checked it in wikipedia for g711ulaw it is 64 Kbps (wiki : G.711 is a narrowband audio codec that provides toll-quality audio at 64 kbit/s.). 160 bytes is nowhere related to 64 Kb.

What is the actual bandwidth used in this case for this call?

Thanks David, this helps me a lot.

So according to the link you have given, for one call it uses 11.2 kbps right?

That depends on L2 and L3 headers
