We have finalized MPLS VPN of full mesh network across all the branches for the data,voice and video.
We are planning for asterisk implementaion for the inter-office voice communications not the problem is we have not done cabling for voice ports as of now we have only cable structuring done only for data.
All the intercom connections around 75 is connected to the EPBAX now we are going for MPLS VPN have doubts
1. Should we get the cable structuring for the voice ports by laying cat6 cables
2 Is it possible to use the existing setup that is all the digital phones to work for interbranchs voice communications and also the same phone can be used or receiving calls from external world and calling for the external world other than the MPLS.
