Hi,
Iam facing some problems in sending faxes to multiple locations through Cisco Gateway. Dial-peer voice configs
are shown below. following is the summary:-
1) Cisco Gateway-1 connected to Meridian 51C PBX. Signalling T1 Qsig.
2) Cisco Gateway-2 connected to Meridian 51C PBX Signalling E1 CAS.
3) Both are connected on MPLS backbone.
4) Link does not seem to have errors since ping of 1500 bytes gets through with 0 errors.
5) Fax machine connected to FXS port is also going thru but not thru PBX.
6) Fax messages getting distorted or error messages.
7) Between 2 locations in Qsig is working ok.
8) Voice is perfectly fine.
Thanks and best regards,
Sarangan
