Hi,

Do you have DNS servers configured on our CME router? Are you able to resolve sip.telecoms.com to IP Address from your CME? If you are not able to resolve sip.telecoms.com then configure IP Address instead of hostname. 

Try below configuration on your CME router:

!
voice service voip
 no supplementary-service sip moved-temporarily
 no supplementary-service sip refer
 supplementary-service media-renegotiate
 sip
  bind control source-interface  <Interface> ------------------> Bind SIP Signaling Interface
  bind media source-interface  <Interface> ------------------> Bind SIP Media Interface
  header-passing
  registrar server expires max 600 min 60
  privacy-policy passthru
!
dial-peer voice 9000 voip
 description ** INBOUND CALLS from telecoms **
 session protocol sipv2
 incoming called-number .
 voice-class codec 1  
 voice-class sip early-offer forced
 dtmf-relay rtp-nte
 no vad
!
dial-peer voice 100 voip
 description **** OUTBOUND CALLS to telecoms *****
 translation-profile outgoing SIP
 destination-pattern 9T
 session protocol sipv2
 session target sip-server
 voice-class codec 1  
 voice-class sip early-offer forced
 dtmf-relay rtp-nte
 no vad
!

Also, make sure you have correct IP Routing configured to reach your ISP.

[moustafa.idc]

yes I'm able to ping

[Vaijanath Sonvane]

Have you tried other configuration. Can you post inbound and outbound call logs for below commands:

• debug ccsip messages
• debug voip ccapi inout
• debug dial-peer

[moustafa.idc]

Here is the debug output, I applied the config you sent already.

calling from IP phone 5020 to 912146043977 and the other direction from +12146043977 to 5020 (02037752050) UK

Thanks for your help!

[moustafa.idc]

Here is the full config

[Vaijanath Sonvane · Accepted solution]

Hi,

For incoming call you are receiving 02037752050 from service provider. In your configuration it is matching dial-peer 9000 but there is no outbound dial-peer. Please apply below configuration:

!
voice translation-rule 11
 rule 1 /^02037752050$/ /5020/
!
voice translation-profile PSTN_INCOMING
 translate called 11
!
dial-peer voice 9000 voip
 translation-profile incoming PSTN_INCOMING
!

For outbound calls, change below configuration:

!
voice translation-rule 1
 rule 1 /^9\(.*\)/ /\1/
!

Once you test again, please post outbound and inbound logs separately. 

[moustafa.idc]

Incoming call is working now. outgoing call from IP phone to the outside is not.

here is the debug message

debug file I did a test from ip phone 5020 calling 912146043977/90012146043977

Appreciate the time and efforts you spent.

Thanks

[Vaijanath Sonvane]

Hi,

I see that you marked this post as accepted solution. Is your outgoing calls working?

[moustafa.idc]

Hi Vaijanath ,

It worked for inbound (so 50 % is done)

I posted the call debug for the outbound if you can get a chance to look at along with the SIP parameters that we need to configure.

Please let me know.

Thanks alot for your great help!

Here is the SIP Parameters that the provider is asking for:

UK Endpoint:
You can send your INVITE requests to our primary UK SIP endpoint: sip.bluetelecoms.com
Authentication:
Every INVITE request is authenticated with digest authentication:
● username - user
● password - pass
Destination Numbers:
Recipient numbers must be in E.164 format: eg: 443334445558 (UK) / 19178103989 (US)
Caller ID / CLI:
Set the Caller Line Identity (CLI) in the From header using E.164 format.
Example: From: <sip:443336783333@sip.bluetelecoms.com>
Codecs
The following codecs are supported:
● PCMA / G711a
● PCMU / G711u

Carrier ID:BT-IN01

Protocol:SIP

[BT-IN01]
insecure=invite
type=friend
context= <YOUR_CONTEXT>
host=bt-in01.bluetelecoms.com
canreinvite=no
qualify=yes
disallow=all
allow=ulaw
allow=alaw

[Vaijanath Sonvane]

Hi, 

Can you post your latest configuration of your router?

[moustafa.idc]

Here is the current config

also I'm looking at the debug below

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

Is it telling us that user/pass is incorrect?

the provider says that they reply the data and get '401 Unauthorized' from us

Appreciate the time you spend to solve this issue

Thanks,

Moustafa

Hi,

Please try below configuration:

  registrar server expires max 3600 min 60

Try below add-on command to earlier config if above configuration doesn't work:

sip-ua 
 calling-info pstn-to-sip remote-party-id number set 4718367014

Please post logs for "debug ccsip messages" commands only.

[moustafa.idc]

Hi

Here is the debug output, looks like same issue for the outbound calls.

Apprecaite the time you spend here!

Thx
