[cisco-voip] Recovery on timer expiry...

[Tamer Mohamed Bayomy]

Dear All,

Two Cisco routers are connected as follows:

VoIP--> R1-->ISDN--> R2 -->VoIP

 

Appreciate any ideas or recommendations to get successful calls from R1
to R2?

 

The Problem: When the call leaves R1 to R2 over the ISDN link in between
i see the call coming on R2 and then disconnected with the following
disconnect reason:

Cause i = 0x82E6 - Recovery on timer expiry

 

R1 config:

---------------

!

interface Serial4/0:15

 no ip address

 encapsulation hdlc

 no logging event link-status

 isdn switch-type primary-net5

 isdn overlap-receiving T302 5000
