I have the 4 OpenVOX B100P ISDN Card on a Elastix 2.4.0 rel 2 version. This system serves total 4 ISDN Lines with total 10 numbers. I use mISDN for the telephone system. Elastix is fully updated with all latest package versions. The codecs i am using is alaw & ulaw specifically assigned in the 2 iax2 extensions i have !
I sent over a days more than 5000 faxes in groups of 100. I have a lot of fax issues in a group. The error codes are below:
1. requeued: No response to PPS repeated 3 times.
2.Failed: RSRPEC error/got DCN
3. Failed: Failure to train remote modem at 2400 bps or minimum speed
4. Failed: Unspecified Transmit Phase C error
Is there any way to solve those errors ? What shall i do to solve them ?
