Description:The V.110 application (see issue 15175) wants to know the User rate specified in the Bearer Capabilities.

With an mISDN channel this gets put into a MISDN_URATE variable. With Dahdi I *see* it...
{noformat}
PRI Span: 2 < Bearer Capability (len= 8) [ Ext: 1  Coding-Std: 0  Info transfer capability: Unrestricted digital information (8)
PRI Span: 2 <                              Ext: 1  Trans mode/rate: 64kbps, circuit-mode (16)
PRI Span: 2 <                                User information layer 1: V.110 Rate Adaption (33)
PRI Span: 2 <                                Async: 1, Negotiation: 0, User rate: 9.6 kbit/s (0x8)
{noformat}
... but there seems to be no way for app_v110 to get access to it.

Libpri does not pass that information up to chan_dahdi.

Per Richard, we'd need a patch to libpri to be submitted to expose this functionality. Would you be willing to submit that patch?
