I've got quite a few in the field that are doing PRI and Voice T1. They work great provided that the customer's PBX vendor will give you the correct config. If you use a TA900E series router you will need a T1 Crossover cable when you connect to the customer's PBX. I spent an hour trying to figure that out after we upgraded a customer from a TA908 to a TA908E late one evening. :) Richey -----Original Message----- From: voiceops-bounces at voiceops.org [mailto:voiceops-bounces at voiceops.org] On Behalf Of Eric Hiller Sent: Sunday, January 02, 2011 9:35 PM To: voiceops at voiceops.org Subject: [VoiceOps] Adtran 924 PRI Does phone equipment see the Adtran 924 PRI as a true PRI? Ie. can this be used in place of a true PRI? Are there any hangups I should know about? I was just going to use this to provide PRI to a customer over SIP rather than have to run a PRI as well. Any advice with the 924? -Eric _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org https://puck.nether.net/mailman/listinfo/voiceops
