Re: SIP trunk between india & Europian country

Technically speaking this is possible (SIP trunk between CUCM<->CME and toll-by-pass calling) and implemented by many Companies.

This topic is widely discussed on the Community, you may check the post below:

Hi,

 

Technically possible, but as per indian regulatory TRAI, its not allowed.

Re: SIP trunk between india & Europian country

It's allowed but making a call like this is illegal:

User in India makes a call to Germany and call flow:
India > SIP TRUNK > Germany cme > Germany PSTN

 

That is toll bypass. Because the India person can make a local Germany call from India. 

 

It's easy to set up a CoS to prevent toll bypass while allowing intercompany communication between IP phones.

Hi Vijay,

you can use cube to allow voip to voip calls over vpn link...as per trai in india, you are not allow to toll bypass of calls..
for inter connecting with france and india branches you can go with cube to allow voip to voip trunk ..

else you can migrate india sites to cucm and establish inter cluster trunk and go for in between office over vpn...

another option if want to use sip trunk in india, please contact your telco that might give you solution to deliver you call over mpls to another country there trai rule not bind and from there you can forward call to PSTN over sip trunk..
