[cisco-voip] Recovery on timer expiry QSIG

[Ahmed Elnagar]

Thanks a lot, but I think 120000 is the default for this timer, how do you
have it showing in the configuration?

Here is what I have been using for my QSIG Connection.  You will see it has
the T310 timer in it.

 

int ser 0/0/0:23

no ip address

encapsulation hdlc

isdn switch-type primary-qsig

isdn timer T310 120000

isdn protocol-emulate network

isdn incoming-voice voice

isdn bind-l3 ccm-manager

isdn outgoing ie facility

isdn outgoing ie notify-indicator

isdn outgoing display-ie

no cdp enable

!

 

I have had it running for about 5 years with no problems.

Hi;

 

I have a PBX connected to CUCM using MGCP QSIG, some random calls "only from
PBX to IP Phones" is dropped after 4 or 5 seconds of the start of call to be
connected "both parties hear each other".

 

In debug isdn q931 I got the below

 

Dec 19 12:01:53.820: ISDN Se1/0:15 Q931: RX <- SETUP pd = 8  callref =

                Plan:Private, Type:Subscriber(local) 

        User-User i = 0x00FE, 'U', 0x0100, 'Y', 0x0100B00C07, 'I', 0x81,

Dec 19 12:01:59.456: ISDN Se1/0:15 Q931: TX -> DISCONNECT pd = 8  callref =
0x826D 

        Cause i = 0x80E6 - Recovery on timer expiry

 

Do you think changing T310 timer will solve this or maybe it is another
issue?
