Get fast busy signal

Volodymyr Khrystenko · ‎10-04-2013

Hello. I have next scheme:

Cisco 9971(1000) ---- Cisco 3945 -------- Cisco 2910 --- Cisco 7742G(1001)

Between two Cisco routers I configured dial-peers and it seems to be working (debug voice dialpeer shows success on both routers). But when I call from 1000 to 1001 or vice versa, I get fast busy tone. Could any one provide any suggestions what could br wrong?

Config is simple:

dial-peer voice 1001 voip

destination-pattern 1001

session target ipv4:10.2.4.254

codec g711alaw

And

dial-peer voice 113 voip

destination-pattern 1000

session target ipv4:10.2.4.120

codec g711alaw

Hello

Please can you use under the dial-peer codec g729r8, not g711alaw?.

Thank you

please rate all useful information

Volodymyr Khrystenko · ‎10-04-2013

I tried it already - no use(((

jfernandorosa · ‎10-04-2013

Hi Volodymyr,

Do you have in this scenario, SIP and H323 for calls.

Ckeck in voice service voip (sip to h323 calls, and redirect ip2ip and trust list) features enable.

Ex:

voice service voip

ip address trusted list

ipv4 10.1.32.0 255.255.255.0

allow-connections h323 to h323

allow-connections h323 to sip

allow-connections sip to h323

allow-connections sip to sip

redirect ip2ip

Regards.

J Rosa.

Yeap, I have such config already, but nevertheless it does not work(((

I tried to set codec everywhere to the same value but the result is the same(

jfernandorosa · ‎10-05-2013

Hi,

The configs already in your router, ok! In destination router the config is same or no?

If possible, describe the your scenario CME X CME and attached configs the router A and B.

Regards.

Did you check whether u can ping between routers.

Thanks

cuteteddy.jain · ‎10-06-2013

Can you share the show run from both routers?
