The modem doesn't recognize the difference between the ring types:

This call came in on the normal ring:
06/27 17:08:51 yS2  waiting for ``RING_'' ** found **
06/27 17:08:51 yS2  waiting for ``RING_''
06/27 17:09:01 yS2  timeout in chat script, waiting for `RING_'
06/27 17:09:01 ##### phone stopped ringing (rings=1)

This call had the distinctive ring:
06/27 17:19:03 yS2  waiting for ``RING_'' ** found **
06/27 17:19:03 yS2  waiting for ``RING_''
06/27 17:19:13 yS2  timeout in chat script, waiting for `RING_'
06/27 17:19:13 ##### phone stopped ringing (rings=1)
