Have a CS1000B branch office v7.65 not completing IP calls. Phones will ring but drop. Analog lines seem to be working OK. Network switch was just replaced because of PoE failure.
Getting err008 in history:

Not sure what's going on.
 
I found this old report below. It was a setting on the newly provided Cisco switch.

Problem
New Rls 5.5 switch
IP to TDM fail with err008

Answer
Cisco switch programming

Typical DDI into MGC using 96 port DB out over the TLAN to a Cisco router then on to the IP set
The IP set rings - CSA - Call drops & err008 seen

Description of err008 from NTP's
ERR0008 tn1 tn2 Call drop due to IPTN failure.
TN1 - PTN
TN2 - VTN
Action:
Severity: Major. Critical to Monitor: No. SNMP trap: Yes
The TN's in the ERR008 were the I/C DDI Trk and the 96 port DSP port TN.

Tried another MGC card but that didn't fix.
Tried another 96 port DSP board but that didn't fix.
From a TLAN port on the IP Tele side of the Cisco switch it was possible to Ping the MGC DSP TLAN IP, but you couldn't Ping the actual MGC Board TLAN IP.

We then put the MGC and the IP set into a standalone HUB and you could Ping all TLAN IP's
This showed a problem with the Customers Cisco switch.

Customer then fixed.
The customer said that on the Cisco the MGC Board TLAN IP address was in a 'Voice' VLAN but it needed to be in both a 'Voice' VLAN and an 'Access' VLAN. (Access VLAN is a Cisco term)
Once the MGC TLAN IP address was added to the 'Access' VLAN then the call matured as it should and no ERR008 message was seen.

OK, my network admin replaced an old Cisco 3560 with an Alcetel model. Some of the vlan'ing configuration is slightly different than on the Cisco. I do have these switches working on SRG sites but not branch office sites. I'm not a networking expert, but I think there is some port trunking that needs to be either on or off for this to work. I confirmed that I can't ping the MGC card, that would be on the elan or tlan?
 
Got it figured out. The port had 802.1q encapsulation enabled.
