Number of Calls over ISDN VGW 2921

[Homayoun Baghestani]

Hi ,

ISDN VGW 2921

We have changed from ISDN to SIP gateway two months ago, but we still use ISDN for backup.

Now I would like to know how many calls we got over ISDN since last 2 months , what can I do for this (we have asked our provider about a detail report for the last 2 months but no chance , they didn’t save the Call records because we didn’t order this)?

If it is not possible for last 2 months , can I collect  the number of incoming call over isdn for the next 2 months ?

Thank you for your answer

Best Regards

Homayoun

Enable logging/syslog and start/stop records for the ISDN calls should appear.

For example:

7585268: Dec 14 10:41:27.429 EET: %VOIPAAA-5-VOIP_CALL_HISTORY: CallLegType 1, ConnectionId 5C5058B1DFE111E7B982C89C1D893390, SetupTime 10:41:06.759 EET Thu Dec 14 2017, PeerAddress xxxxxxxx, PeerSubAddress , DisconnectCause 10  , DisconnectText normal call clearing (16), ConnectTime 10:41:27.399 EET Thu Dec 14 2017, DisconnectTime 10:41:27.399 EET Thu Dec 14 2017, CallOrigin 2, ChargedUnits 0, InfoType 2, TransmitPackets 990, TransmitBytes 166320, ReceivePackets 990, ReceiveBytes 158400

You can also enable SNMP traps to monitor when you ISDN PRI is being used:

interface Serial0/0/0:15
 logging event link-status
 snmp trap link-status

Hi Georgios,

Thank you for your Response.

How is with the sizing of the log file if I need the number of calls for 2 months , I think if I created a small file for logging , it will be overwritten , correct?

It shouldn't take much of space Homayoun. You can even store this locally, only, on router's buffer. Each entry is only a few bytes size and as you say your PRI is not used much. Of-course, you should configure logging buffered accordingly.
