In Cisco IOS , you have the option to put in place your own command with the command alias .
Don’t be shy to use it as it can be fun for the long expression or command that you have problem to remember / to type .
Here are some examples :
alias configure ns no shut
alias exec scavb show call active voice brief
alias exec sdvs show dial-peer voice summary
On VG224 , you can choose asymetric G711 codec with the voice service voip command for the fax issues.
voice service voip
modem passthrough nse codec g711alaw
The modem passthrough commands will determine the G711 mode used for outbound calls
But the following part of config will determine the codec use for inbound calls :
dial-peer voice 15 voip
description <=== avoid PVID 0 in VG224 ==>
modem passthrough nse codec g711ulaw
session target ipv4:<<loopback_address>>
So in our case , the incoming calls will considered in g711ulaw and outgoing calls will be treated as g711ulaw
Never forget to use the answer-address or incoming called number to remove the use of the PVID 0.
Especially when you want to negotiate your codec and VAD.
