I want to deploy the following scenario:
My Telephony Service Provider give me a Digital E1 (30-channels PCM) on Main Site and I want to receive them with a router and VWIC-1MFT-E1 to transmit via ethernet to another site with other router with VWIC-1MFT-E1 to connect with one PBX. I am going to use G.729 codec in ethernet media to reduce bandwidth. I am a little confuse of I must take care about transcoding issues for router's dimensioning.
Thanks in advance for any help and tips.
