Really looking for some help on a very strange issue I'm having.
Customer has a 2800 series router connected through 2 FXO cards (7 extensions) to their local phone system. Seven remote sites have a 1751 router connected through a single FXO port (as CO line) to their own phone system. This is a analog--->digital---->analog setup to utilize their antiquated phone systems through their network for VOIP inter-office calling.
Reprogramming for these routers was basically thrown in my lap (I'm the premise phone vendor), after the new IT company told them they do not support Cisco. I bit the bullet and gave myself a crash course in Cisco 101 and was successful in reconfiguring the routers for the new IP address scheme 3 months ago. Functionality was perfect.
Today, the 2800 was accidentally power cycled and now there is one-way audio only for inter-office calls. I've checked the configs, rebooted, etc. Still no luck.
I spent an hour on the phone with the local IT support and we could not find any problems with the routing. I am able to ping all the outside routers from the 2800 and vice-versa. Yet, if a place a call to one of the remote sites, I can hear them but they are unable to hear me.
Am I looking at a hardware issue here? My experience has been that one-way audio issues are inevitably network related, but there have been no changes to the network. Only the power cycle on the 2800.
I've attached a copy of the 2800 config if you're interested in seeing it. Please note though, this EXACT config worked flawlessly up until the 2800 was rebooted.
ANY help would be surely appreciated.
