Thanks to the list for the help about the "+" substitution. will it be implemented in version 2.2.x? I see some other users working with Cisco ATA. we have two voice gateways connected to PSTN for outbound calls (one is a cisco 2650 with NM-HDV, and a PRI access; the other is a cisco 1751V, with three FXO cards and analog lines), a bunch of terminals (digicom, cisco ata, netmeetings) and a GnuGK 2.07 in H225 routed mode in between. when I call from digicom or netmeeting both voice gateways, everything is fine. when I call from the ATA the analog lines, everything is fine. if I call from Cisco ATA the PRI gateway, gnugk accepts the call, but then the ATA drops it with the following log (I just hide the phone numbers): .......... active @0xa28006f (GK @0xa250002) [0]StartTone 0 [0]DTMF 0 , insum:....
