New sip service - calls disconnecting after a few mins

[faghouri83]

Hi Everyone

Im not an expert on SIP so would really appreciate any help on my problem.

Basically a new sip service has been installed and cube routers have been configured by the itsp. We can make calls inbound and outbound but after a few mins, the call just drops. It seems to be affecting all users. Sometimes the call lasts 6 mins, sometimes 9 or even 2 mins. Completely random. Ive noticed an error code on the debug and was wondering if anyone could take a look for me please.

THanks

Hi,

          Did you checked the internet speed (both upload and download) whether it is alright when there is connection loss.

Thanks

Hi,

From the logs called number is 08448933910 calling number is 012541 ...CUBE is disconnecting the call  because your provider stopped responding to sip options ping. CUBE sent a total of 7 SIP options ping to your ITSP and it didnt not get any reply and after about 6 minutes on this call, CUBE disconnected the call.

You need to speak to your ITSP to know why they stopped responding to options Ping. You may also increase the duration that CUBE sends options ping..Or you could disable it altogether and test again.

Hi

Before I ask the ITSP and do some troubleshooting, could anyone tell me the difference between

voice-class sip options-ping 60

and

voice-class sip options-keepalive down-interval 60 retry 3

thanks

They do the same thing..I think the first command is an old one..You should be using the options-keep alive command

voice-class sip options-keepalive

#
