Hello all, We are evaluating different SS7 solutions ready for production deployment and we have some questions regarding chan_ss7: 1. Echo canceling We saw the options regarding echo canceling inside ss7.conf. What will happened if we choose to use a digital card equipped with an echo canceling module? It will work or not? 2. Bellow is a proof of concept proposal and the corresponding configuration file. Basically we will use 2 machines (each with 2x1E1 cards) for signaling (S1 and S2) and 3 machines (each with 2x1E1 cards + echo canceling modules) for voice (V1, V2 and V3). All 5 machines will have 2 Ethernet interfaces: one for management and VoIP traffic (if-1) and one for cluster traffic (if-2). The cluster will be monitored by the signaling nodes. We hope to achieve with this architecture (split between signaling and voice nodes) a maximum for redundancy and flexibility. Could you send your advices about the proposed ss7.conf file? 3. Which should be the maximum number of voice spans which you recommend to have on the voice nodes? We plan to use 2x4E1 cards (without g729 hardware trans coding) or 1x8E1 + trans coding card (in case we choose g729 hardware trans coding), hoping not have a "storm of interrupts". We are hoping to receive your comments and recommendations regarding the mentioned issues.
