Hi Group,
Various places we have seen Voice access-list but strange its not
working in my config:
R7 ----IP Network ----- R2
Config of R7:
dial-peer voice 70 pots
destination-pattern 7777
port 4/0/0
!
dial-peer voice 20 voip
destination-pattern 2222
session target ipv4:204.100.100.177
R7#sh runn int s6/0.5
Building configuration...
Current configuration : 147 bytes
!
interface Serial6/0.5 point-to-point
ip address 204.100.100.146 255.255.255.240
ip access-group 101 in
frame-relay interface-dlci 705
end
R7#sh acce
R7#sh access-l
R7#sh access-lists
Extended IP access list 101
permit tcp any any eq 1720 (22 matches)
permit tcp any eq 1720 any
permit tcp any eq bgp any (16 matches)
permit tcp any any eq bgp (25 matches)
permit udp any any range 16384 32767 log
permit ospf any any (65 matches)
COnfig or R2:
R2#sh runn | begin dial-pee
dial-peer voice 20 pots
destination-pattern 2222
port 1/0/0
!
dial-peer voice 70 voip
destination-pattern 7777
session target ipv4:204.100.100.146
!
!interface Serial0/0.5 point-to-point
ip address 204.100.100.177 255.255.255.240
no ip directed-broadcast
frame-relay interface-dlci 205
Symptoms:
1. Voice call gets established but no RTP / UDP packet transfer.
*You can not hear the opposite end voice)
2. If I add one more line in ACL 101 "permit tcp any any",
everything works fine and I could see UDP packet log also...
Which extra port do I need to open for End-to-End communication?
regards....Prakash
