<span style="font-size: 11pt; color: rgb(31, 73, 125);">Hey Folks,<br><br>Kind of strange issue here, tied to some other stuff I've posted about. Anyway, does anyone know how to set ptime or where that is configured? <br>
<br>Please forgive if this is staring me in the face somewhere, I've not found anything satisfactory just looking around. But, I am slow sometimes. <br><br>What's up? We have an FS that has two incoming numbers. One of them, just recently, started doing the following (from our VoIP ISP tech guy):<br>
<br>All calls that
work (to the second number) network originates the call with maxptime=20, we
respond with ptime=20 and everything works fine. The calls that do not
work (primary number) network originates the call with maxptime=30, we
respond with ptime=30 then immediately re-invite with ptime=20. I
suspect somewhere in this re-invite either your switch or our provider’s
switch is getting confused and not sending or processing RTP based on
the re-invite.<br><br>Result? The caller can't be heard by the call taker at our FS. Plus, the sound quality, even of the ring, is bad. <br><br>Sorry so long a post! Right now, we're forwarding the "bad" number to the "good". A band-aid. Any ptime experts here? We did not change this parameter, but did modify the call_timeout up to 19 from 15 trying to give 'em another ring. Then back down once this started to no avail. <br>
<br>Thanks for reading this far if you did. Any advice appreciated. <br><br><br></span>
