Any ideas on the following occasional errors we get on Cube?
1. SIP-3-INTERNAL: Cannot insert call history entry for callID : 24857223
2. SIP-3-NOMATCH: Unable to find matching CCB for ccCallID
3. VOICE_IEC-3-GW: SIP: Internal Error (1xx wait timeout): IEC=1.1.129.7.59.0 on callID x
4. SIP: Internal Error (ACK wait timeout): IEC=1.1.129.7.67.0
Is there a error document on Cube that I can review ?
