Yes. You have been caught by a not-very-well-documented issue with setting up voice routing on the 3845, and probably other similar Cisco gear. And I'm not sure how you've done your test. This is the closest I've ever seen to a document that explains your problem: http://www.cisco.com/en/US/tech/tk652/tk90/technologies_tech_note09186a0080147524.shtml Did you have a SIP phone on one side of asterisk and a POTS phone on the outside of the 3845? If you did, and you could talk on both at the same time, I think you would discover in fact that you do have some audio, in fact, one-way audio to be precise. But I don't remember for sure, because it's been a while since I've done this to myself. At any rate, your problem is you have dial-peers to get voice packets out from the 3845 to Cisco, but no dial-peers to get the packets from SIP back to a physical circuit on the 3845. Think about this. What should happen to a call inbound from asterisk, to the 3845? Should it go out an E1 to the outside phones world? If so, you need to build a dial-peer that does that. Until you do, you won't be getting two-way audio. you need another rule something like: dial-peer voice 790792888 pots map this back to the proper E1 circuit A secondary problem could also be with the way you're managing your DSPs. I don't know how many physical DSPs you have in your router, but usually it's a GOOD thing to enable DSP farming. _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
