OK, so have a few FXS ports reserved for alarm outbound calling. That could work, but I was hoping to capitalize on the existing PRI connection.

Or is call manager in between the call due to MGCP or VOIP dialpeers involved in the dialplan ? I doubt your issue is line voltage, since you can see the call being placed. My guess is the DSP is processing the call and causing issues. I've seem alarm boxes use nonstandard DTMF transmission that isn't properly recognized by the DSP. The 2800 supports DSP bypass by default when you route directly between ports using POTS dialpeers. You do need to have properly configured network clock configuration. Can you send a copy of your config along with the output of 'show controller t1' and 'show network-clock' Justin On Feb 28, 2015 10:33 PM, "chris" < [email protected] > wrote: <blockquote> Hey Ryan, We have a channelized T1 with channels split between voice/data so the voice path is TDM.

Someone recommend this adapter offlist which looks interesting but the price is a little nuts as it costs more than all the equipment we have installed at this site combined. http://www.homedepot.com/p/Viking-1-Line-Long-Loop-Adapter-VK-LLA-1/204399995 Chris On Sat, Feb 28, 2015 at 8:18 PM, Ryan Huff < [email protected] > wrote: <blockquote> Chris, Can you diagram the connections for me? Are the copper pairs swinging off a 66 block before terminating to the alarm panel or is there a direct copper path between the fxs port and the alarm? Are you using an RJ-11 or RJ-14 configuration? Could you estimate the copper distance between the termination points? Is the pstn path for the VG SIP or TOM? Also, I would be curious to know if the alarm panel is a Simplex Grinnell? Thanks, Ryan -------- Original Message -------- From: chris < [email protected] > Sent: Saturday, February 28, 2015 07:52 PM To: [email protected] Subject: [cisco-voip] FXS voltages / POTS compatibility Hello We have a location with a 2800 acting as a voice gateway where we have 2 FXS voice ports going to an alarm system. We are using the vic-4fxs/did line card. We have the alarm company saying they are seeing the panel reporting Comm trouble so we checked the call records and we also did some debugging in realtime and we see the calls are going out and when we plug a test set in the dial tone is good. In talking with the alarm company and researching we have come to believe the issue may be due to the idle and ringing voltages. We came across this link: http://www.cisco.com/c/en/us/support/docs/voice/analog-signaling-e-m-did-fxs-fxo/28280-ring-idle-voltages-fxs.html This looked promising however when we are in voice port configuration node we do not have the idle-voltage setting available. We tried several iOS versions in 12.4 as well as 15.x hut no luck Is this line card not capable of -48 idle voltage? What cards are? Do we need anything special as far iOS version? Ideally we want to have 2 voice ports that are as close to a standard pots line as possible. We are a bit lost as its the first time we have hit an issue like this and we are just hoping someone has been down this path before. If we have to change line cards or even to another platform we are open to it as long if someone has a setup that is known working in this manner Thanks in advance Chris </blockquote> </blockquote> </blockquote> <blockquote> _______________________________________________ cisco-voip mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-voip </blockquote> _______________________________________________ cisco-voip mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-voip
