Hi, I had connected my FreeSWITCH server to ePBX using sanoma A102DE, and installed wanpipe drivers and loaded freetdm module with the below configurations. When I tried to make an outgoing call to a PBX extension(PSTN) I got the following error. <application action="bridge" data="freetdm/wp1/16/1000"/> 2012-08-13 14:47:54.172568 [ERR] ftdm_io.c:1921 Failed to open channel 1:16 2012-08-13 14:47:54.172568 [NOTICE] mod_freetdm.c:1622 Close Channel N/A [CS_NEW] 2012-08-13 14:47:54.172568 [NOTICE] switch_ivr_originate.c:2544 Cannot create outgoing channel of type [freetdm] cause: [NORMAL_CIRCUIT_CONGESTION] Please help me out in solving this problem.
