I am thinking about a solution to be provided to one of our customers, please check the attached design.
Such implementation is easy to implement, but there are some questions in my mind:
1) In case of link X failure, will SRST routers register to GK and be able to call Site B and Mitel? And can SRST routers call each other through the IP network?
2) Can I register the Voice GW connecting Mitel directly to gatekeeper, so that all sites and branches can call Mitel?
3) In case of GK failure while all links (including X) are working, are the other components will be able to call each other.
Thanks in advance.
