dcbour Posted February 8, 2007 Share Posted February 8, 2007 I just installed Uplink yesterday but am having consistently choppy sound on the incoming sound. According to the people at the other end, it sounds fine to them. I see a couple of posts regarding this, but no replies. In my case, it's a Trixbox install. I've got a VTech portable Skype phone running off the same system where the Uplink and Skype are installed. Sound quality is fine there. The Asterisk is a Trixbox 2.2 installation, no zaptel devices (ie, for timing). I've only configured it for outgoing calls at this point. My other trunk on the system runs flawlessly. Any suggestions as this is unusable in this state. Thanks in advance Dave Link to comment Share on other sites More sharing options...

Dave Hi Dave Trixbox here too (v. 1.2.3) with Zaptel board and no problem with choppy sound. Asterisk on a Linux server Uplink on a Windows server SIP phones are Linksys SPA942 on all work stations This is my Trixbox trunk settings in case it could help: allow=ulaw canreinvite=yes context=from-trunk disallow=all host=dynamic nat=yes ;very important. uplink won't work without this secret=xxxx ;define your own password as in uplink type=friend username=xxxx ;make sure this is same to trunk name Good luck, Georges Link to comment Share on other sites More sharing options...
dcbour Posted February 12, 2007 Author Share Posted February 12, 2007 Had type = peer, changed to friend, no change. Checked if I had ztdummy module loaded, shows in the lsmod list. Can't think of anything else. Any help / suggestions appreciated. Of note...10-20% of calls from internal sip softphones are fine...balance are choppy...any call routing through via disa ALWAYS choppy. Thanks in advance D.

cvega99 Posted February 27, 2007 Share Posted February 27, 2007 username=xxxx ;make sure this is same to trunk name The above did it for me. As soon as I made the user name the same as the trunk it worked well. I have one problem though. When I use express talk I can dial out because I dial 9+1(AREACODE)NUMBER However if I use a regular line or a DISA from outside I don't have a "+" to prefix the number. Is there a way to prefix a + for this trunk in Trixbox? Or can this be done from the dial section in the UPLINK software? Thanks in advance.

I am also having very choppy sound with The Uplink with the following setup: Skype (windows) -> Uplink (windows) -> Asterisk 1.2 (Linux) -> Zaptel -> Old ISDN PBX -> Old Digital office phone The following setup gives perfect sound though: Skype (windows) -> Uplink (windows) -> Sipura adaptor -> Normal analog phone Anyone have any idea why sound is choppy through asterisk/Zaptel? Bad timing or something? //z_smurf Link to comment Share on other sites More sharing options...

markosjal Posted April 17, 2009 Share Posted April 17, 2009 Still have this problem with calls coming from zaptel. Anyone has a fix ??? Sip is perfect More than likely this is because asterisk 1.2 has no real jitter buffers. This may affect your connections are far from the internet backbone. You may be able to minimize this effect by setting up reinvites. canreinvite = yes, among other prerequisites. This depends much on your configuration however which I know little about.
