[cisco-voip] Ideas for cheaper international calling

If you are placing SIP trunks at remote sites you need to do CUBE for survivability. If you a trunking directly from an off-site CM... SRST is pretty much useless because you are not terminating the trunk locally.

Add TelePacific to your list.  Currently we have certified CME, Asterisk, Allworx, Shoretel, Toshiba, Avaya, Siemens, Linksys, and are in the process of certifying Mitel, for SIP Trunking (and more in the pipeline for 2010).  Thankfully the Marketing folks at my company listened and we are deploying ISR's running CUBE for every install now to trunk into Broadsoft Broadworks.  We originally attempted to certify with a handful of firewalls but the NAT traversal problems were different based on the IP PBX being tested and would be a nightmare to manage what works and what doesn't.  Eventually we narrowed it down to Pix/ASA firewall required but of course there are many customers with Sonicwall (among others) who did not want to swap.  Now we drop in an ISR parallel to the customers firewall so they can keep their existing hardware, have the customer give us a private IP for one Ethernet port on the ISR, and the PBX SIP Trunk points to the ISR and we handle the rest.  CUBE is a life saver!

I opened a TAC case 613141081 and they confirmed you need a CUBE for the username/password.

So in short Skype for SIP is not certified for Cisco CallManager, but is certified for Cisco Unified Border Element (CUBE).  Devil is in the details, but I feel no reasonable small business looking at Skype understands the benefits of CUBE feature licensing and will want to run direct to CallManager and will look at Paetec, Broadsoft, Verizon, Packet or any of the many Skype to Gateway solutions out there.... my personal opinion -jason

In CallManager 7.1 where do I input SIP realm settings for the Trunk to Skype?

You can use SIP realm settings to create username and passwords for this.

I expect a low cost provider like Skype isn't going to have any support!

I signed up for Skype for Business and started to set up Skype for SIP tonight direct to a CallManager 7.1.3 box (no CUBE), I'm not clear where in CCMAdmin I can enter my Skype username/password, or if a CUBE is required for authentication.  Anyone else setup Skype for SIP and have some tips?

Since CallManager is certified I expected Skype's website to have some advice, but the best you get is contact the PBX manufacturer...

Other than using MSN and Yahoo or skype point to point for free, there are no completely free options out there.  At least, none that are legal.

Hello all,

I know this isn't strictly Cisco Technical but was hoping you all could help me out.

We have a US-based Call Center that will start making hundreds of international calls each day and we don't want to pay the phone company (surprise), we don't have VoIP in the countries we need to call so TEHO won't work.  There are a ton of online services and Skype for SIP, anyone have any experience with beating the system with creative solutions that avoid the toll?

Thank you in advance and a good weekend to all!

Mike
