Cisco cme sip trunk configuration


In general this is quite simple, have done this before several times. After a lot of debugging the debug 'debug voip ccapi inout' tells me this:. Jun 15 So far fro debugs, it seems that dial-plan was good, then next step is to establish connectivity to ISP to send the invite message. It seems that connection attempt failswith remote server, so we are not able to see INVITE message itself in debugs.

Had a quick look, at options being printer, which we usually use as keep alive message for remote end:. Usually most of the telcos gives an WAN ip address for sip communications. I don't really understand the options send by CME, I would like to disable that. This is an older router, and I have not seen this before on CME. Don't think it is needed. Also SIP stack is throwing many message incomplete errors, where it says something receivedbut is unable to read that:. Shall try a little more on the 28xx router, but it seems this provider is not compatible with this way of configuring.

I did some searching and I found that this error is no route to destination. There is a small ADSL router in front, maybe this device does something ugly. Buy or Renew.

I have this problem too. Amit Kumar.I could see that my Third Party Phone has got an extension and i could also verify the same in the CME by typing the below commands. Note:- The configuration only shows the registration of Third Party SIP Phones but however it wont perform call routing until and unless other necessary configuration are done.

I had a recommendation from cisco support that in this case nothing should be added under sip-ua:. If your ITSP does not provide credentials, your sip-ua probably does not register at all. I think if you configure registration, the dial peers pointing to the sip-server target will be down if registration fails. Actually nothing changed with the configuration proposed by you.

Can anyone explain the below messages:. Call-ID: q41r7a55rrsq8e4q4l4qr1el84a68s6e 1.

When I try to make a call nothing happen. I type the number and nothing, I even do not hear any dial-tone at all. When I try inbound calls I receive "network failure".

I thought that "session target sip-server" is same as write " session target ipv Isn't this true? It sounds like the outbound call attempt isn't matching a dial peer. Currently your outbound dial peers expect the dialled number to start 99 and to pass the whole dialled number to the provider.

Difficult to be more specific with out knowing your country's numbering plan, and the format the provider expects. You can use the command "show dialplan number xxx time" to show which dial peers, if any, are matched by a particular dialled number. Obviously xxx should be your dialled number. If you mean secondary dial tone, to be played after you've dialled the PSTN access code then that needs to be specifically configured. I have specified the clid network-number xxxx under dial-peer just for testing purposes.

And destination-pattern 99T for outbound calls. So I type xxxx when I make the test. The dial peer command "clid" sets the calling number presentation, nothing to do with the dialled number or the destination.

I'm not even sure wildcards are supported. Your dial peer destination pattern is 99T, meaning any number starting with 99 followed by any further digits until inter-digit timeout.

Login to Cisco Unified Communication Manager. To do this follow the below shared steps. The settings has to be done on Asterisk PBX. Published by Team UC Collabing. Thank you. Well done. It works. Hello Baris, Thank You for confirmation. The above steps guides how to create an outbound dial pattern which routes the call from Asterisk to CUCM and vice-versa.

Let me know if you still have questions. I believe i need to do some custom thing to dial it. I am also unable to work on the lab due to hectic schedule.

Now, create as a DN in Elastix and Forward calls to the extension Hope the above solution makes sense. If you would like me to think of a different solution, probably i would have to work on your network taking control of your Elastix using Team Viewer. Let me know whatever is feasible. Hello Thanks for the explanation.

I have downloaded the Asterisk from asterisk site, but do you suggest any specific site to download the whole package and the patches. X and CUCM 8. X with Elastix v2. X and it worked fine.

Hope this helps! Hello Sophorn, What error are you getting while setting up the trunk? Are you facing issue with inbound or outbound call from CUCM? Please check the parameters thoroughly once again as this configuration has worked for most of the people who followed this blog.

You will not require a translation rule for outbound since you will be sending a single number. I hope this document will be useful to you. If you like the post please rate. Tags: cme. Hall of Fame Master.Today, the telecommunications industry is in the process of making the transition from long establishing switching and transport techonologies to IP-based transport and edge devices. The IP communication revolution has started to create a tremendous commercial impact in small and medium businesses.

These small and medium businesses are realizing that the use of IP is very efficient because IP can use Voice, Video, and Data capabilities over a single network, instead of using three separate special-purpose networks. Figure 1 shows an IP telephony deployment trending towards IP trunking. These successive translations increase the maintenance costs of the gateways, increases latency, and reduces voice quality.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared default configuration. If your network is live, make sure that you understand the potential impact of any command. Refer to the Cisco Technical Tips Conventions for more information on document conventions. SIP is an ASCII based, application-layer control protocol that can be used to establish, maintain, and terminate calls between two or more endpoints.

SIP has rapidly emerged as the standard protocol used in IP communications, because it is a multimedia protocol that can be used for video sessions and instant messaging in addition to voice. Also, SIP can handle conference sessions and broadcasts, as well as one-to-one sessions.

SIP has great potential in transforming and developing the way people communicate.

Configure a SIP Trunk between Cisco CME and Cisco CUCM

For this reason, Cisco has and continues to play an important role in taking a leadership to create new technologies that make SIP and its applications the standard of IP communications. In order to access the IP network using a SIP trunk, it is necessary that configurations be made on the service provider, as well as on the customer side. The reason is that a customer faces challenges in handling different interpretation and implementations of SIP by equipment vendors, delivering security, managing quality of service QoSenabling Network Address Translation NAT and firewall traversal, and ensuring carrier-grade reliability and continuity of service.

CME permits small and medium businesses to deploy voice, data, and video on a single platform. Therefore, by using CME, small and medium businesses can deliver IP telephony and data routing using a single converged solution with minimal costs. A DTMF distortion existed between the two devices. When CME 3. Another important aspect to consider when you set up an SIP trunk is the codecs supported. Codecs represent the pulse-code modulation sample for signals in voice frequencies. SIP trunks support these codecs: G.

This means that voice calls that use SIP trunks using codec G. MOH can also use codec G. This is due to the fact that G.

Therefore, you must force MOH to use G.May 10, Leave a comment. Before this, if you want to know how to add ephone and ephone-dn in CME follow this post :.


To configure a SIP Trunk, we need to configure two dial-peers one for incoming call and the other one for outgoing call. In the dial peer for outgoing call, we set the destination pattern which specifies the route pattern to reach our phones on CUCM, so 1….

Use default configuration for all parameters. With a wireshark trace, we can see by default G codec is used. Also, CME stays in the media path. You are commenting using your WordPress.
