One way voice issue dilan@dpmce.com - SYSTEMS ENGINEER, DPMC ELECTRONICS PVT LTD.
Aug 7, 2003, 3:19am PST I have tried setting up a basic Voip configuration between 2 branch sites using 2 service PRovider networks using Cisco 1750
routers. One setup was over a frame relay network and the other over a PPTP tunnel link that goes through several intermediate
routers. The setup worked fine on the frame relay n/w. Over the PPTP link however,the calling party doesn't get the ringback although
the phone at the other end rings. When the called party answers, he can hear the calling party but the latter doesn't receive
the voice stream. This was always the case. With some debugging I found that the called party sends the RTP voice stream to the wrong RTP port at the calling party. The
port nos were always 2 greater than the correct one. Eg:- called party sends the voice stream to 18002 when the calling party's end shows that its RTP port should actually be
18000. There was no port mismatch the other way. Has anyone faced this problem?

Voip call will wait long time (12 seconds) to get ring back tone mishao - Network Engineer, NETSTAR TAIWAN
Aug 5, 2003, 7:44pm PST hi, I setup 2* 3725 with alcatel PABX (T1 cas).the voip call is fine. But the problem is that we required to wait 12 seconds to
hear the ring back tone. attached configuration. best regards. fred. TTNTaiwanQuanta#s run Building configuration...

Aug 6, 2003, 11:01pm PST The longer than expected post-dial delay could be incurred by the interdigit timeout due to the command destination-pattern
37T. The "T" option instrUCts VoIP GW to wait for 10 seconds before completing digit collection. Try destination-pattern
37....(actual number of dots depends on the number of digits in the number)to remove interdigit timeout
