ERR008, CS1000E, rls 5

[nortelcs100e5]

Hi i am getting ERR008 4 0 5 0 8 1 5 4 randomly and call between cabinets got silent or no speech path. Then TN`s are random but this error is between cabinet to cabinet only, with cabinet ext to ext call is OK, it is cs1000e rls 5. Can somebody point a right direction to resolve this?

ERR0008 tn1 tn2
Call drop due to IPTN failure.

TN1 - PTN
TN2 - VTN

Severity: Major

If this is a Media Gateway based 1000E, then I would say you should check the settings on your DSP Daughterboards and VGMCs to make sure you can route IP between them.

Hi pal, My MC32s is programmed as VGW channels, this error occurs when i created a zone1 and zone 2, i put all SIP trunks in zone2 and tried to put Mc32s in zone1, previoulsy mc32s was in zone 0. I then deleted zone -1 and EDD then restarted PBX and got every thing OK.
Any advise??

I have always been told that zone 0 is for soft phones only.

Having the SIP trunks in zone 2 is fine. I would advise creating a new zone for the MC32s. Make sure it is a shared zone, so devices in other zones can use the channels.

Remember, in a 1000E cabinet to cabinet communication is IP, so TDM resources in cabinet A must use a DSP to talk to anything outside of that cabinet (IP phones, and TDM resources in other cabinets). If your DSP's are not registered, or there are routing issues between the cabinets, you will have problems.
