Hi all, I am trying to figure out if it is possible to configure call-foward no answer while in SRST mode to the PSTN.  Essentially, my offices call-forward to an answering service at 5pm each night for afterhours phone coverage.  If we have a network outage and the router falls back to SRST, and somebody calls, the phone will ring forever.  What I would like to do is program it so that after x amount of rings, it will call-forward out to another one of our offices, which, if after hours will then relay it to the answering service (or if its during hours, one of our staff will be able to help the caller).  Can this be done?  I've found an article by the excellent William Bell that would address the afterhours part, but from my understanding this would fire all the time while in SRST, not after a timeout (article here http://www.netcraftsmen.net/component/content/article/70-unified-communications/802-redirecting-called-numbers-in-srst-the-alias-command-and-hairpin-methods.html) I'm using CUCM BE5000 8.6.1 with 2901 ISRG2 routers using MGCP if it helps. Thanks in advance. Bill ... View more

Hi everybody.  Could anyone give me some pointers on what works for them when using a standard analog line connected to an FXO card on a Cisco 2901 gateway, MGCP controlled by a UCM BE 5000 8.6?  The fax machines are connected on an FXS card in the same router. When the fax machines use the PRI, we achieve 100% success, but when faxing over the FXO analog lines, we get about a 50% failure rate with the fax machines reporting "poor line quality."  Just for grins, the lines are directly connected right now and they do not report any line quality problems until we try to move them onto the gatewway. If it helps any, in port configuration on the CallManager we have echo cancellation disabled, input gain at 0, output attenuation at 3.  For the gateway, we have modem passthrough enabled, Cisco fax relay disabled, T38 Fax relay disabled, RTP Package enabled, MT package disabled, RES packaged disabled, PRE package enabled, SST package enabled, RTP unreachable OnOff Enabled, and Type of DTMF relay is "current GW config." Any pointers on how to get this more reliable would be appreciated. ... View more
