Hi,
A client of mine has been having ongoing intermittent call drop outs for a few years now and whilst a little random as to when they happen, there are 2 consistencies in the dropped calls. She can and has had calls that last longer to these types of numbers though - such is the intermittent nature of the problem. I had posted this problem some years ago when it first happened but it was ignored! Now she has emailed me again with another dropped call. The last one prior to this that I’m aware of was on the 13/1/14 to 1300 150 300 (Macquarie bank) for 11 minutes and 11 seconds.
Whilst this is annoying the worst part is that as these calls go into a call centre, it takes 10 minutes to wade through the IVR system and to be on hold before speaking to a earth creature, then once the call gets dropped you have to start the call all over again – this is when my client gets very annoyed and I get the resultant email!
The nature of the dropped call is as follows:
- The call is dropped after 11 minutes 10 or 11 seconds – exactly.
- The called number is to a 13 xx xx, 1300 xxx xxx or 1800 xxx xxx, typically these numbers will belong to the call centre of an Australian business with the call being made from Melbourne, although the geographical location of the call centre may not be in Australia, although most banks etc. would be. The number in this instance is to Westpac bank
The call statistics page in her Quadro 2x is shown as getting a “bye” message to end the call from the called party – which is when the call is dropped.
If there are any more clues in the SIP UA log attached I would be very interested to know as I would a fix for the problem too. Her network setup is very basic and orthodox, with just the WAN port being used on the 2x going through the Cisco RV042 router and a bridged Netcomm NB6 modem, with a business nDSL and VOIP service provided by iiNet.net.au
Attached is the SIP UA log a screen dump image of the current call stats would be attached but for the upload size limit!
If anyone can shed some light on this I would be very grateful.
Thanks, Francois.
PS. The first person to suggest a firmware upgrade will have their goolies cut off!
