B-ACD i cant hear from outside via SIP

[Ahmed Zein]

Dear All,

     i have CME router 2811 "Router 1"

CME           Version 7.0(0)

IOS              Version 12.4(15)XZ2

B-ACD configured under dial-peer 100 "H323 not SIP"

my connection to GW is via Dial-peer 8, SIP not H323

Topology as follow:

"GW"------SIPv2------"CME Router1"------IP Phone

1-from inside IP phone i can call 73432789651 "B-ACD number" and can hear the voice of welcome message.

          so there is no Audio files issue

2-from outside, i.e via SIP; call connect but i cant hear the voice of the message

voice service voip

Hints;

1- i tried to make dialpeer 100 use SIP and didnt work, i even cant hear from inside, also i cant hear from inside  if i changed the g711ulaw codec at Dial-peer 100.

2-sip to gateway is a must. i cant use H323 as my GW is a provider and i face many issues with h323

please try to help me as much as you can, it is very urgent issue and crucial.

Dear Vandan;

     all debugs requested are uploaded to my profile/documents

https://supportforums.cisco.com/people/Zeinovich?view=documents

hints:

B-ACD dial peer is 100, not the other dial peers, there is old dial peers in the configuration not used.

1- all these calls done from another city phone number 73462555512

2-i have created a SIP trunk to Provider gateway "dial peer 4321" just to separate the issue and change as much as i can

3-from internal phone i can call  73462555512

4-from internal i can hear the B-ACD welcoming and press digits to select the options

5-from outside "i.e 73462555512," i cant hear welcoming message , and cant press digits to select the options, i.e DTMF not working, not just voice of welcoming message of B-ACD

6-i cant see any H323 signaling or something, does the b-ACD dial-peer 100 use H323 or what??

Hi Ahmed,

Could you please run all the debugs same time and collect in one file. If we have all the debug collect same time, i can see where excatly is issue.

Please log all of this to the router's buffer with these commands: 

config t

no logging console

no logging monitor

no  logging rate-limit

no logging queue-limit

logging buffer 3000000 debug

After turning on the debugs, issue the command "clear log".  Then reproduce the issue.  After that, dump the contents of the log using: term len 0 show log

many thanks for your help, my friend

Hi Ahmed,

Can you have your provider send the rtp-nte or sip-notify for DTMF. I don't see either in invite.

Would you please try the following changes:

dial-peer voice 100 voip

service aa1

sess pro sip

destination-pattern 73432789651

session target ipv4:192.168.1.1

incoming called-number 73432789651

dtmf-relay rtp-nte sip-notify

codec g711ulaw

[Ahmed Zein]

Dear Vandan,

A::FROM MY SIDE

1- i modefied the dial-peer 100 by adding

dtmf-relay rtp-nte

but i cant add sip-notify, as it is unrecognized command!!!

2-how can i add sip-notify

B:FRM PROVIDER SIDE

1-i didnt ask them yet, but what exactly should i ask ?

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

D:why there is no H323  signaling in he debugs??

Hi Ahmed,

I found one old bug, whcih should be fix by now, But still want to see if media is not playing because DTMF is not nego. To confirm you can try the workaround mentioned here. But for DTMf to work in any case, you would have to contact the provider to support it. You can also try the T train IOS.

CSCsj67507

CME BACD Does not work when comming in SIP

Symptom:

A sip call to a B-ACD script will not hear the Audio 

Conditions:
If DTMF-RELAY is not configured on the inbound dial-peer 
or if DTMF-RELAY is not negociated.

Workaround:

Both sides need to be configured with rtp-nte or sip-ntfy
If the Sip provider doesn't support DTMF-RELAY , 
you will have to loop the call to a h323 dial-peer 
and define Service under the h323 dial-peer.
configuring DTMF-Relay is the best option unless drop through prompts 
are configured

Vanda, I am really cant find words to thank you man

i will do your solution,

and it will resolved "In shaa ALLAH"

but please , can you clarify the 2nd solution, the workaround? how the loop dial-peer can be donem my frien?"

[vandana]

Hi Ahmed,

With this workaround, you would be able to hear media but DTMF still won't work, for that you need to contact your provider.
