VoIP over Frame Relay

Hi all,

I'm trying to configure VoIP over Frame Relay like in this configuration:

interface Serial0/0

ip address 192.1.1.100 255.255.255.0

encapsulation frame-relay

ip ospf authentication

ip ospf authentication-key 7 xxyyzz

ip ospf network point-to-point

delay 30000

frame-relay traffic-shaping

frame-relay map ip 192.1.1.200 101 broadcast

frame-relay interface-dlci 101

class voip

frame-relay lmi-type ansi

frame-relay ip tcp header-compression

frame-relay ip rtp header-compression

map-class frame-relay voip

frame-relay cir 64000

frame-relay mincir 64000

no frame-relay adaptive-shaping

frame-relay fair-queue

frame-relay fragment 250

frame-relay ip rtp priority 16384 16380 64

!

The rpoblem is when I establish one conversation and I send data (ping between two stations) the 'debug ip rtp header-compression errors' show me this mesage:

01:13:08: RHC Serial0/0: Bad sequence context3: expected sequence 14, received

sequence 15

I'm working with 12.0XK IOS version on two 2621 Cisco Router.

What can it happens? I'm making somethhhing wrong?

Thanks in advance.

Re: VoIP over Frame Relay

Often times complex troubleshooting issues are best addressed in an interactive trouble-shooting session with one of our trained technical assistance engineers. While other forum users may be able to help, it’s often difficult to do so for this type of issue.

To utilize the resources at our Technical Assistance Center, please visit http://www.cisco.com/tac and to open a case with one of our TAC engineers, visit http://www.cisco.com/tac/caseopen

If anyone else in the forum has some advice, please reply to this thread.
