[cisco-voip] calls dropping on 5th minute

[Voll, Scott]

Could the service parameter have gotten changed?  In 4.1 it's 12hours
:-) maybe it got changed to 5 minutes?

 

Why don't you use clock external.

 

Scott

Hi to all

Here is the problem

I have 2811 connected through WVIC-MFT-E1 to the telco using ISDN PRI
service.

IPT using CCM 4.2.

Every call I made out and in to the PSTN gets dropped on the exactly 5th
minute (300 sec) with cause code 127 interworking error

I get slips on the line:

 

R2811-B#sh controllers e1 0/0/0

E1 0/0/0 is up.

  Applique type is Channelized E1 - balanced

  Description: BTC_PRI_LINE

  No alarms detected.

  alarm-trigger is not set

  Version info Firmware: 20051006, FPGA: 20, spm_count = 0

  Framing is CRC4, Line Code is HDB3, Clock Source is Internal.

  CRC Threshold is 320. Reported from firmware  is 320.

  Data in current interval (788 seconds elapsed):

     8 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail

And here is the configuration:

 

controller E1 0/0/0

 linecoding hdb3

 framing crc4

 clock source line

 pri-group timeslots 1-31

 

interface Serial0/0/0:15

 no ip address

 encapsulation hdlc

 isdn switch-type primary-net5

 isdn overlap-receiving

 isdn incoming-voice voice

 isdn send-alerting

 isdn bchan-number-order ascending round-robin

 no cdp enable

end

 

 

The telco said that this is not their problem.

Any suggestion might be useful.

Thanks in advance
