People,

I’m tring to use 2 e-1 in Brazil. In order to get R@ signaling, I compilled libdsp, unicall and stuff following www.soft-switch.org <http://www.soft-switch.org/> comparing with another site (Dezert of Zazamora, in Mexico). Asterisk is running fine with Asterisk but I can’t make calls.

The guys on the telco company tells me that I have a LOMF (Loss of Multi Frame) error in their end (the far-end) and we can exchange digits. They expect R2-Digital signaling and they think the implementation I use is not quite right.

When I try to make a call the result is as follows:

Nov 11 12:02:13 VERBOSE[3451]: -- Executing Dial("SIP/200-3ced", "UNICALL/g2/55431100") in new stack Nov 11 12:02:13 DEBUG[3451]: Using channel 1 Nov 11 12:02:13 DEBUG[3451]: unicall_call called - 'g2/55431100'

I’m attaching the three most relevant configuration files. Sorry if is kind of messy (a lot of lines commented out), that is because I tried a lot of things before posting.

If the telco sees a loss of multi-frame sync from your end the problem is nothing to so with the MFC/R2 code. Either you have the zaptel.conf set incorrectly, or your line is faulty, or a card is faulty.
