I have a Cisco 3845 with PVDMs and VWIC 2MFT-T1 cards. I need to terminate some voice circuits from an Avaya G3R switch. This needs to talk to a SIP endpoint. So far I have got the SIP configuration worked out (I think). I am having issues getting the T1 configued from the Avaya. My current controller looks like this:
controller T1 0/1/0 framing esf linecode b8zs
I entered the command:
ds0-group 0 time 1-24 type e&m-wink-start
to get the interface to come up with no errors as shown below:
glc-rtr2-atl#sh controll t1 0/1/0 T1 0/1/0 is up. Applique type is Channelized T1 Cablelength is long gain36 0db No alarms detected. alarm-trigger is not set Soaking time: 3, Clearance time: 10 AIS State:Clear LOS State:Clear LOF State:Clear Version info Firmware: 20060711, FPGA: 13, spm_count = 0 Framing is ESF, Line Code is B8ZS, Clock Source is Line. CRC Threshold is 320. Reported from firmware is 320. Data in current interval (13 seconds elapsed): 0 Line Code Violations, 0 Path Code Violations 0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins 0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail
This is only going to be used to pass inbound voice through SIP to a phone switch. My SIP config looks like:
voice service voip sip
dial-peer voice 1 voip preference 1 destination-pattern . session protocol sipv2 session target ipv4:192.168.69.200:5060 codec g711ulaw no vad ! dial-peer voice 2 voip preference 2 destination-pattern . session protocol sipv2 session target ipv4:192.168.69.210:5060 codec g711ulaw no vad !
I cannot get a definite answer from TAC on whether or not this is a valid configuration. I usually only do data. My previous configuration on the T1 interface looked like:
controller T1 0/1/1 framing esf linecode b8zs channel-group 0 timeslots 1-24 ! This gave me my familiar serial lines but had tons of errors. Which one should I be using? Any help is appreciated.
