Not in my case. The captures sounded fine, it wasn't until metaswitch said they found an issue with old polycom fw that I was able to solve the problem. It was like the metaswitch was ignoring the packets. The problem was exactly the same, 1st ~5 seconds of silence towards the pstn. Not on every call but easily reproducable. The fw they upgraded to was 3.1.2 I believe. On Jan 5, 2010, at 11:49 PM, Matt Yaklin <myaklin at g4.net> wrote:

I forgot, we had this issue with invalid RTP sequence numbers with old Polycom firmware. Are you using Polycom phones?
If that was the case would not his captures of the traffic and the resulting replay be mangled at every point me mentions below?

I trace a call?on my cell phone I hear the first 1 -2 seconds clipped?however the trace sounds fine?.
Traced at SBC side facing Level 3
Traced at SBC side facing Customer (who receives inbound call)
Traced at Customer Prem
All the above 3 traces the Audio sounds fine, but on my cell phone I miss the first 2 seconds.

Have you captured via wireshark and replayed? Do you hear the same delay? Is there a delay between the OK (answer) and the audio? On 1/5/2010 8:22 PM, Ujjval Karihaloo wrote: Hi Guys;
We have noticed that sometimes when calling into our DIDs (Level 3 DIDs), there is a 2-3 second lag. i.e. Cell phone caller (party A) calls into a DID (Party B) that is on our network (Broadsoft Softswitch), Party B answers and sayd 1,2,3,4,5 ? but the Party A only hears 4, 5?The part i.e. 1,2,3 get cut off.
Plus it is sporadic and difficult to reproduce, was wondering if folks have encountered this and any good troubleshooting techniques you can recommend.
