RichardDCG Posted February 16, 2022 Report Share Posted February 16, 2022 We also have Grandstream UCM managing some inbound fax to email and these are quite solid. Their email format is a let down though. Vodia has a better email format but faxing is not as reliable. The UCM seems to include ECM but the Vodia does not. In a PCAP capture in T.38: The UCM has: data:v17-14400: hdlc-data[xxxxxxxxxxxx...] hdlc-fcs-OK (HDC Rassembled: FCD - Facsimile coded data- Frame num:XX) Vodia has: data:v17-14400: t4-non-ecm-data[xxxxxxxxxxxx...] Are there any areas I can look at to improve reliability?
