Sir,
belowBelow, I've attached a list of Cisco licenses and devices to provide VoIP connectivity. Cisco 4321 router with SRST and CUBE licenses will provide the ability to terminate traffic also to the local numbering zone. As subscriber terminals, we recommend Cisco 8851.
The telecommunications operator will set up a link (100 Mb / 100 Mb) with parameters and codecs as specified by you. The IP address will be kept in the new location and local telephone numbers will be transferred (to SIP).
What kind of technical support do you expect from us at the stage of starting connection with the Call Manager server? Will the configuration of terminals and voice call routing be carried out remotely? Is a dedicated SIP link (separate from the Internet) required?
