I'd think your goal at this point should be to simplify the config to the smallest possible config that can produce the questionable behavior, and then provide that entire config file (even better, implement this in docker compose, using something like sipp to emulate your UAs, so that the behavior can be easily reproduced by anyone). If the config is too big to reasonably present in an email, then just put the sample code on github. Several points with the sample config you cite. This thread subject says that the error is with topoh enabled, but the code snippet presented provides neither module parameters for topoh, nor any call to topoh functions. Why are you asserting that topoh is the problem? Your second line is a call to route(REQINIT), with no information on what happens in that route. While we can guess that it's the same as the default config file, there's no way to know for sure. It's also not clear why the nat functions and add_path_received() are in this config as it relates to this problem. Start removing all of this for problem isolation until you can identify where the problem is occuring. I'd also be curious if the error in question is really a result of parsing the ACK or if it's something else (trying to pull $ru off of a reply generates some kind of error like this I think). Finally, although it's not the RURI, WHAT is with the scheme on the URIs in your To: and From: headers? 'Mailto"?

If I take your example and set the ACK R-URI to match the contact of the 487 the problem looks to clear. SHOULD this be required, I'm not sure. I've never used topoh, but I'd say to check this in your real-world examples comparing working phones to non-working phones.

As suggested I created a repository, so as to recreate the problem. https://github.com/beres/kamailio_tmp_topoh To/From all seems normal to me, which is why I don't understand. Maybe it has nothing to do with topoh, but if active in certain cases it doesn't work. This is a copy of an ACK taken from production ``` ACK sip:rs4xe4w4@client_ip:2048;line=kkqgarrj SIP/2.0 Via: SIP/2.0/UDP proxy_ip;branch=z9hG4bKc4aa.897ab3d4c4434cc636cb12e0c390a81a.0 Route: <sip:kamailio_ip:5060;lr;received=sip:client_ip:2048> Max-Forwards: 66 From: <sip:phone_number@domain.tld>;tag=y3QX10D10tyQH To: <sip:rs4xe4w4@domain.tld>;tag=31fhufhtrn Call-ID: 04b3fa08-b9b4-43fe-b04a-cbe03bd5dc2d CSeq: 90508938 ACK Content-Length: 0 ``` Thank you On Thu, Oct 24, 2024 at 3:45 PM Ben Kaufman <bkaufman@bcmone.com<mailto:bkaufman@bcmone.com>> wrote: I'd think your goal at this point should be to simplify the config to the smallest possible config that can produce the questionable behavior, and then provide that entire config file (even better, implement this in docker compose, using something like sipp to emulate your UAs, so that the behavior can be easily reproduced by anyone).
