[Asterisk-Users] MFC/R2 in the Philippines

[Dido Sevilla]

I've been struggling with getting the soft-switch.org Unicall/MFC-R2
implementation working. After wading through some misleading
instructions and a build process that leaves much to be desired in
terms of reliability and consistency (e.g., the order in which the
various libraries should be compiled is plain wrong: I believe it
should be spandsp, supertone, unicall, and mfcr2 in that order) , I've
finally managed to get a working chan_unicall.so module used by
Asterisk.  From searching through the mailing list archives, I see
that I seem to have gone a good deal of the way, up to the point where
I see the "warnings" about channels being unblocked on the near and
far ends when * starts. However, when I attempt to initiate an
outbound call with Asterisk, it suddenly fails with what I gather is a
congestion error. "no one is available to answer at this time".

I am quite certain it is not a problem with the E1R2 we are using, as
it had previously been in use on a Nortel PBX and was working fine
there. I'm trying to use the Philippine R2 variant.

Does anyone have a sample configuration that works for the
Philippines? Any help on this is much appreciated.
